Stereochemistry of cyclic compounds

The diene condensation of 1-vinylcyclohexene with the ethylψ -ester of malealdehydic acid was carried out: it goes structurally and sterically selectively and leads to the adduct (III) with a cis-syn configuration.
A study was made of the hydrolysis and isomerization of the adduct (III) and of the corresponding saturatedψ-ester (IX) into the isomericγ-aldehydic acids having a free aldehyde group at C2.
