Abstract

Compounds of general formula I, <IMAGE> [wherein R represents a hydrogen atom or an alkyl radical containing from 1 to 5 carbon atoms; X represents a hydrogen or halogen atom or an alkyl radical containing from 1 to 5 carbon atoms; Y represents a hydrogen atom or an alkyl radical containing from 1 to 5 carbon atoms; and Z represents a hydrogen atom or an alkoxy radical containing from 1 to 5 carbon atoms; with the proviso that at least one and no more than two of X, Y and Z represents a hydrogen atom; and salts thereof] possess anti-allergic activity. They are prepared by decarboxylating the corresponding 1,2-dicarboxylic acid mono-ester derivative.
