A mechanism for the isomerisation of ethyl 1-ethoxycarbonyl-2-oxocyclopentylacetate (I) into a cyclohexane β-keto-ester as proceeding through an intermediate bicyclic /gb-diketone (VII) has been considered as an alternative mechanism to one earlier suggested.1 The determination of the structure of the isomerised β-keto-ester as 2, 3-diethoxycarbonylcyclohexanone (V) has provided support for the earlier mechanism.

Starting from 6-methoxynaphthaldehyde-2, 2-carboxy-7-methoxy-1, 2, 3, 4-tetrahydrophenanthrone-4 was prepared. Sodium borohydride reduction of the keto-acid followed by chromic acid oxidation yielded the lactone of 2-carboxy-4-hydroxy-7-methoxy-1, 2, 3, 4-tetrahydrophenanthrone. Alkylation of the lactone of 2-carboxy-4-hydroxy-6-methoxytetralone was not promising.

The ultraviolet spectra of α-carboxy and α-carbomethoxystilbenes obtained in the Claisen/Stobbe reaction of methyl phenyl acetate and aromatic aldehydes is reported. All these compounds possess the characteristic

The Perkin-Oglialoro reaction was used for the synthesis of α-aryloxycinnamic acids, but the yields were very low. The potassium tertiary butoxide catalysed condensation of aryloxyacetic ester and aldehydes leads to the formation of
