Abstract

Important intermediates: In an effort to synthesize and determine the stereo-chemistry of pinnaic acid, C14-epimeric aldehydes 1 and 2 were generated from Meyers' lactam 3. A key step in the parallel syntheses is a highly stereoselective vinylogous Michael cyclization; Boc = tert-butoxy carbonyl, TFA = trifluoro-acetic acid.
