Compounds of general formula I ,(I) wherein R1 and R2 represent alkyl or cycloalkyl groups or together with the nitrogen atom to which they are attached, represent a cyclic imino group, R2 represents a hydrogen or a halogen atom, an optionally substituted hydroxy, mercapto, amino, carboxy or aminocarbonyl group, or a nitro, alkanoyl, aminosulfonyl, trifluoromethyl or cyano group, R4 represents a hydrogen atom or an alkyl group. R5 represents a hydrogen or a halogen atom or an alkyl group, A represents a bond or an optionally substituted methylene, ethylene or vinylidene group, B represents a methylene or ethylene group optionally substituted by an alkyl group and W represents a hydrogen or a halogen atom, a cyano, alkanoyl or nitro group, an optionally substituted amino or aminocarbonyl group. a carboxy group or an ester thereof, a formyl group or an acetal thereof or an optionally substituted alkyl group); and salts thereof formed with acids and bases. Processes for the preparation of the new compounds as well as pharmaceutical compositions containing them are also objects of this invention. The new compounds show valuable pharmaceutical properties, especially effects on intermediary metabolism and a blood-sugar lowering activity.
