Reactions of ethyl cinnamates with arylacetamides gave the corresponding 2,6‐diketo‐3,4‐diarylpiperidine ( 1a‐o ) in addition to the corresponding cinnamides ( 2a‐o ) and arylacetates ( 3a‐o ). The latter two are formed from the intermediates of the Claisen condensation of the reactants. On the other hand and contrary to the above results, condensation of p ‐methoxycinnamate with arylacetamides gave only p ‐methoxycinnamide in quantitative yields with the corresponding arylacetates.
