Description
Die Erfindung betrifft neue 2-Alkyliden- und 2-(Alkyl-1-en)-cyclopentanone, ihre Verwendung als Riechstoffe sowie parfümierte Produkte und Riechstoffmischungen enthaltend die erfindungsgemäßen Verbindungen, sowie ein Verfahren zu ihrer Herstellung.The Invention relates to novel 2-alkylidene and 2- (alkyl-1-ene) cyclopentanones, their use as fragrances as well as perfumed products and perfume mixtures containing the compounds according to the invention, and a process for their preparation.
In der Riechstoffindustrie besteht ein nachhaltiges Interesse an der Entwicklung von neuen Riechstoffen, um somit die Kreation von neuen Parfümölen für die alkoholische, wie auch funktionelle Parfümerie zu ermöglichen. Verbindungen mit blumigen Geruch sind hierbei unverzichtbare Komponenten in der Duftstoffindustrie. Eine besondere Klasse dieser blumigen Riechstoffe sind Verbindungen mit blumig-jasminartigen Noten. Strukturell zeichnen sich Verbindungen mit blumig-jasminartigen Noten in manchen Fällen durch einen Cyclopentanon-Ring aus, der in α-Position durch einen Alkyl- oder Alkylen-Rest und in β-Position durch einen Methylacetat Rest substituiert ist. Die zwei wichtigsten Vertreter dieser Klasse von Riechstoffen sind die natürlich vorkommenden 3-Oxo-2-pentyl-cyclopentyl-essigsäuremethylester (II) (Methyldihydrojasmonat, Hedione®, Firmenich S.A.) und 3-Oxo-2-(pent-2-enyl)-cyclopentyl-essigsäuremethylester (III) (Methyljasmonate). Ein weiterer Vertreter dieser Substanzklasse ist 3-Oxo-2-pentyl-cyclopent-1-enyl-essigsäuremethylester (IV), diese Verbindung wird aber weniger als Riechstoff, sondern vielmehr als Vorprodukt für die Synthese von 3-Oxo-2-pentyl-cyclopentyl-essigsäuremethylester (II) eingesetzt.In the fragrance industry, there is a sustained interest in the development of new fragrances, thus enabling the creation of new perfume oils for both alcoholic and functional perfumery. Flowery odor compounds are indispensable components in the fragrance industry. A special class of these flowery fragrances are compounds with floral-jasmine-like notes. Structurally, compounds with flowery-jasmine-like notes are sometimes characterized by a cyclopentanone ring which is substituted in the α-position by an alkyl or alkylene radical and in the β-position by a methylacetate radical. The two most important members of this class of scents are the naturally occurring 3-oxo-2-pentyl-cyclopentyl-methyl acetate (II) (methyldihydrojasmonate, Hedione ®, Firmenich SA) and 3-oxo-2- (pent-2-enyl) - cyclopentylacetic acid methyl ester (III) (methyl jasmonate). Another representative of this class of substances is 3-oxo-2-pentyl-cyclopent-1-enyl-acetic acid methyl ester (IV), but this compound is less than fragrance, but rather as a precursor for the synthesis of 3-oxo-2-pentyl-cyclopentyl Acetic acid methyl ester (II) used.
Methyldihydrojasmonat (II) zeichnet sich durch eine warme, blumige Jasminnote, gepaart mit der frischen blumigen Weichheit einer Zitrone aus. Methyljasmonat (III), welches ein flüchtiger Bestandteil des Jasminöls ist, besitzt einen starken blumig-krautigen, süßen Geruch, der an Jasmin absolute erinnert. Demgegenüber steht ein schwacher fruchtiger Geruch, der nicht an Jasmin erinnert, für die Cyclopentylverbindung (IV).methyldihydrojasmonate (II) is characterized by a warm, flowery jasmine note, paired with the fresh floral softness of a lemon. methyl jasmonate (III), which is a volatile Component of the jasmine oil is, possesses a strong flowery-herbaceous, sweet smell, the jasmine absolute remind. In contrast, there is a faint, fruity odor that does not remind you of jasmine for the Cyclopentyl compound (IV).
Aus S. Shicheng et al., Youji Huaxue, 1986, 20, 453 ist [2-Pentyliden-3-oxo-cyclopentyl]-essigsäuremethylester bekannt, welcher als Zwischenprodukt erhalten wird, und für die weitere Synthese zu Methyldihydrojasmonat der obigen Formel II und Methyldihydroneojasmonat benutzt wird.Out S. Shicheng et al., Youji Huaxue, 1986, 20, 453 is [2-pentylidene-3-oxo-cyclopentyl] -acetic acid methyl ester known, which is obtained as an intermediate, and for the other Synthesis to methyl dihydrojasmonate of formula II above and methyldihydrone ojasmonate is used.
In WO 2004/043895 wird ein Prozess zur Synthese von Alkylidencyclopentanon-Derivaten (V) beschrieben.In WO 2004/043895 describes a process for the synthesis of alkylidenecyclopentanone derivatives (V).
Hierbei repräsentiert G eine C=O oder C(OR)2 Gruppe, R1 z. B. n-Butyl als reine Alkylgruppe ohne Heteroatome und R2 eine unverzweigte oder verzweigte C1 bis C4 Alkylgruppe. Es wird ausgeführt, dass die Verbindungen der Formel (V) als Zwischenprodukte für die Synthese der oben beschriebenen Verbindungen (II – IV) eingesetzt werden können.Here G represents a C = O or C (OR) 2 group, R 1 z. B. n-butyl as a pure alkyl group without heteroatoms and R 2 is an unbranched or branched C 1 to C 4 alkyl group. It is stated that the compounds of the formula (V) can be used as intermediates for the synthesis of the compounds (II-IV) described above.
Die Auswahl an blumig-jasminigen Riechstoffen, die dem Parfümeur für die Kreation von Parfümölen zur Verfügung stehen, ist sehr begrenzt.The Selection of floral-jasmine fragrances that the perfumer for the creation from perfume oils to disposal are very limited.
Es war deshalb die Aufgabe der vorliegenden Erfindung, Jasmin-Riechstoffe anzugeben, deren Geruchsprofil sich von dem der oben beschriebenen Verbindungen (II – IV) unterscheidet. Vorteilhafterweise sollten dabei die anzugebenden Jasmin-Riechstoffe originelle geruchliche Aspekte aufweisen, um so die für die Komposition von Parfums zur Verfügung stehende Rohstoffpalette zu erweitern.It was therefore an object of the present invention to provide jasmine fragrances whose Ge odor profile differs from that of the above-described compounds (II-IV). Advantageously, the jasmine fragrances to be indicated should have original odor aspects in order to expand the range of raw materials available for the composition of perfumes.
Erfindungsgemäß wird diese
Aufgabe gelöst
durch die Verwendung einer Verbindung der Formel (Ia) oder (Ib): wobei in jeder der Formeln
(Ia) und (Ib)
R1 H oder Methyl und
R2 eine verzweigte oder unverzweigte C1- bis C5-Alkylgruppe
ist,
als (Jasmin-)Riechstoff.According to the invention, this object is achieved by the use of a compound of the formula (Ia) or (Ib): wherein in each of the formulas (Ia) and (Ib)
R 1 is H or methyl and
R 2 is a branched or unbranched C 1 to C 5 alkyl group,
as (jasmine) fragrance.
In den Formeln (Ia) und (Ib) kennzeichnen geschlängelte Linien jeweils das E-Isomer, das Z-Isomer und die E/Z-Isomerenmischungen.In the formulas (Ia) and (Ib) meandered lines respectively the E-isomer, the Z-isomer and the E / Z isomer mixtures.
Als verzweigte oder unverzweigte C1- bis C5-Alkylgruppe kann insbesondere eingesetzt werden: Methyl, Ethyl, n-Propyl, iso-Propyl, n-Butyl, sek.-Butyl, iso-Butyl, n-Pentyl, iso-Pentyl und 3-Methylbutyl. Bevorzugt sind insoweit jedoch die Alkylreste Ethyl, n-Propyl, iso-Propyl, n-Butyl, sek.-Butyl, iso-Butyl und n-Pentyl und besonders bevorzugt die Alkylreste Ethyl, n-Propyl, n-Butyl und n-Pentyl.As branched or unbranched C 1 - to C 5 -alkyl group can be used in particular: methyl, ethyl, n-propyl, iso-propyl, n-butyl, sec-butyl, iso-butyl, n-pentyl, iso-pentyl and 3-methylbutyl. However, in this regard, the alkyl radicals are preferably ethyl, n-propyl, isopropyl, n-butyl, sec-butyl, isobutyl and n-pentyl and particularly preferably the alkyl radicals ethyl, n-propyl, n-butyl and n-pentyl ,
Ein
weiterer Gegenstand der Erfindung sind Verbindungen der Formel (Ia)
und (Ib), wobei
R1 H oder Methyl ist
und
R2 eine verzweigte oder unverzweigte
C1 bis C5 Alkylgruppe
ist, wobei
die bereits aus WO 2004/043895 bekannte Verbindung
der Formel (Ia) mit R1 = H und R2 = n-Propyl ausgenommen ist.Another object of the invention are compounds of formula (Ia) and (Ib), wherein
R 1 is H or methyl and
R 2 is a branched or unbranched C 1 to C 5 alkyl group, wherein

Gemäß einem weiteren Aspekt betrifft die vorliegende Erfindung auch Mischungen, die jeweils zumindest eine Verbindung der Formel (Ia) und eine Verbindung der Formel (Ib) umfassen, wobei der Anteil an (Ia) vorzugsweise größer ist als der Anteil an (Ib). In diesen Mischungen paart sich der an Jasminblüten erinnernde Geruch der Verbindungen der Formel (Ia), mit dem jasminig-lactonigen Geruch der Verbindungen der Formel (Ib) in einzigartiger Weise zu einem unverwechselbaren, komplexen Jasmingeruch. Die Substituenten R1, R2 können in der Formel (Ia) die gleiche oder eine andere Bedeutung haben als in Formel (Ib). Wie weiter unten noch anhand des Syntheseweges gemäß Schema I näher erläutert wird, lassen sich die Mischungen umfassend eine Verbindung der Formel (Ia) und eine Verbindung der Formel (Ib), wobei die Substituenten in (Ia) und (Ib) identisch sind, in besonders wirtschaftlicher Weise synthetisieren.According to a further aspect, the present invention also relates to mixtures each comprising at least one compound of the formula (Ia) and a compound of the formula (Ib), wherein the proportion of (Ia) is preferably greater than the proportion of (Ib).
