Abstract

A process for the preparation of compounds of general formula <IMAGE> (wherein R represents a hydrogen atom or an alkyl radical containing from 1 to 9 carbon atoms and R1 represents an alkyl radical containing from 1 to 5 carbon atoms) which comprises cyclising a compound of formula II, <IMAGE> (wherein R and R1 are defined above and R2 and R3, which may be the same or different, each represents an esterifying group) followed, if required, by hydrolysis to the free acid.
