Aryl-1'-(aryl)-alkyl-methylidene- or aryl-1'(aryl)alkyl-methyl-dicarboxylic acid alkyl ester or their thiocarboxylic acid esters, process for their preparation and their use

摘要

The invention relates to {aryl-[1'-(aryl)-alkyl]-methylidene}- and {aryl-[1'-(aryl)-alkyl]-methyl}-dicarboxylic acid alkyl esters and their thiocarboxylic acid ester analogues of the general formula IMAGE in which Ar1 and Ar2 are, independently of one another, aryl radicals, R1 is a hydrogen atom or an alkyl radical with 1 to 5 carbon atom(s), R2 is an alkyl radical with 1 to 5 carbon atom(s), R3 is an alkyl radical with 1 to 6 carbon atom(s), R4 and R5 are hydrogen atoms or together form another bond, X1 and X2 are, independently of one another, oxygen or sulphur atoms, Y1 and Y2 are, independently of one another, oxygen or sulphur atoms, m and p are, independently of one another, integers from 1 to 8, and the wavy lines indicate that both the E and the Z isomers and mixtures thereof are embraced including their Z and E isomers and optically active enantiomers and mixtures thereof. The invention also relates to a process for preparing this compound and its use for preparing antidiarrhoeal, antibiotic, antimycotic, antisuppressive (antidepressant) and antitumour compositions.
