According to the invention there are provided compounds having the general formula (I):
and stereoisomers thereof, wherein one of X and Y, but not both, is a group of the formula (II):
and the other of X and Y is a hydrogen atom, a halogen atom, or an alkyl, cycloalkyl, cycloalkylalkyl. alkenyl, alkynyl, aryl, aralkyl, alkoxy, aryloxy or haloalkyl group or a
group wherein R9, R10 and R11 can be alkyl, alkenyl, alkynyl, cycloalkyl, cycloalkylalkyl or aryl, Z is an oxygen atom, a sulphur atom or an -NH-group, A and B have the same significance as X or Y excluding a group of formula (II), R'. R2, R3 and R4 each represent a hydrogen atom, a halogen atom or an alkyl group containing from I to 4 carbon atoms, R5 and R6 each represent a hydrogen atom or an alkyl group containing from I to 4 carbon atoms, and R7 and R8 each represent an alkyl group containing from I to 4 carbon atoms or R7 and R8 together with the adjacent nitrogen atom form a heterocyclic ring which may optionally contain an additional hetero atom; and acid addition salts thereof.
