Abstract

Process for the manufacture of new basic 1,3-dioxanes and their salts of the general formula I ** (See formula) ** wherein R 1 is hydrogen or a lower alkyl radical, A a branched or straight-chain alkylene radical, X a benzhydryl group or a 1-phenylcyclohexyl group, while R 2 and R 3 represent hydrogen, aryl or alkyl radicals, which may be also be combined with the C2 atom of the dioxane ring forming a cycloalkyl ring, and its salts, characterized in that a) to 5-amino-dioxanes- (1,3) of the formula II ** (See formula) ** wherein R1, R2 and R3 have the above meaning, they are reacted with halogenated compounds of the formula XA-Hal (meaning of X and A as before), or conversely of this reaction, 5-halogen- dioxanes of formula III ** (See formula) ** wherein R2 and R3 have the above meaning, with an amine of the formula R1-NH-A-X (meaning R1, A and X as indicated above), or b) aldehydes of the formula IV are reduced ** (See formula) ** wherein X has the meaning indicated above and B is an alkylene chain shortened by 1 C atom against A, or the corresponding ketones in the presence of an aminodioxane of the formula II (R1 = H), and optionally subsequently (R1 = lower alkyl), or c) an amide of formula V is reduced ** (See formula) ** wherein R1, R2, R3, X and B have the meaning indicated above, after which, if desired, the dioxanes of formula I obtained are commonly transferred to their salts.
