process for the production of 1 - (aryl or subst. - aryl) amino - 1 - thioalkancarboxylsalzen or the corresponding carboxysaeuren

摘要

The invention relates to 1995 for the preparation of 3 - (n - aryl - n - acylamino) - gamma - butyrothiolactones. / p & & p & the process consists of cleaving the arylamino - gamma - corresponding lactone with a salt of the type in order to obtain the thiolate of arylaminothiolalcane carboxylate corresponding to hydrolyse the salt and a well, the acid in order to obtain the product n - acyl - n - arylamine corresponding. This product is then cyclises to form the composed desire. By way of variant, it is possible to reverse the order of the acylation and the cyclization. / p & & p & the 3 - (n - aryl - n - acylamino) - gamma - butyrothiolactones obtained by the process of the invention are gifted of pharmacological fungicides.
