Abstract

Several series of substituted dehydropiperidine and piperidine-4-carboxylic acid analogs have been designed and synthesized as novel, potent dual PPARalpha/gamma agonists. The SAR of these series of analogs is discussed. A rare double bond migration occurred during the basic hydrolysis of the alpha,beta-unsaturated dehydropiperidine esters 12, and the structures of the migration products were confirmed through a series of 2D NMR experiments.
