その際、R1、R2、R3、R4はさらに付加的にHを表してよく、かつ
R4及び/又はR5=Hである場合には、R1はフェニルではない]で示される化合物の製造方法において、一般式(II)
R1、R4、R5は前記の意味を表す]で示されるエポキシ−カルボン酸アミドを、一般式(III)
R2、R3は前記の意味を表す]で示されるアンモニア又はアミンと反応させることにより、完全に意外にかつこれについて有利には劣らずに課された課題の解決に成功した。こうして得られる一般式(I)の化合物は、高い位置異性体純度の予想に反して、高い収率で、及び − R1≠Hの場合に − ジアステレオマー純度のほぼ完全な維持下に得られる。
R1=(C1〜C8)−アルキル、
R2、R3=H
R4=H
R5=(C1〜C8)−アルキル−(C3〜C8)−シクロアルキル、特にシクロプロピル
として有する式(I)の化合物が合成される。式(II)の脂肪族エポキシ−カルボン酸アミドの使用がさらに特に好ましい。殊に、R1が炭素原子2〜8個を有する線状アルキル鎖、特に線状C3−アルキル基を表す化合物が好ましい。
同様に好ましくは、基R4、R5の少なくとも1つがHではないエポキシ−カルボン酸アミド(II)が使用される。ここでは、エポキシ−カルボン酸−N−アルキルアミドの使用が極めて好ましい。殊に好ましくは、前記方法は式3による3−プロピル−オキシランカルボン酸−N−シクロプロピルアミドに適用可能である。
Rは線状(C1〜C8)−アルキル基を表す]で示される化合物と、キラルな酸、例えばヒドロキシ酸(例えばマンデル酸、酒石酸、ジベンゾイル−酒石酸、ジトルオリル−酒石酸、乳酸)、N−アシル−アミノ酸(例えばベンジルオキシカルボニル−L−フェニルアラニン、アセチル−L−フェニルアラニン)又はスルホン酸(例えばショウノウスルホン酸)もしくはアミノジカルボン酸との塩は本発明のさらなる態様である。好ましくは、式(V)の化合物とマンデル酸及びベンジルオキシカルボニル−フェニルアラニンとの塩が形成される。ベンゾイルオキシカルボニル−L−フェニルアラニンとの塩が殊に好ましい。
式(I)の化合物の遊離塩基は、前記塩から、公知方法、例えば酸−塩基−抽出により取得されることができる。より強い酸、例えば塩酸との塩交換も可能である。
基(C1〜C8)−アルコキシは、基(C1〜C8)−アルキルに相当するが、但し、この基は酸素原子を介して分子に結合されている。
(C2〜C8)−アルコキシアルキルは、アルキル鎖が少なくとも1つの酸素官能基により中断されている基のことであり、その際に2個の酸素原子は互いに結合されることはできない。炭素原子の数は、基中に含まれている炭素原子の全数を規定する。
(C2〜C8)−アルキレン結合は、炭素原子2〜8個を有する炭素鎖であり、その際にこの鎖は、2つの異なる炭素原子を介して、考察された分子に結合されている。この鎖は、飽和又は不飽和の炭素環式の環又は、環系中に窒素原子、ケイ素原子、硫黄原子、リン原子又は酸素原子1〜4個を有する、ヘテロ環式の環を表してよい。
