Abstract
α,β-Unsaturated aldehydes react with monoalkyl malonates in pyridine with a catalytic amount of dimethylaminopyridine (DMAP) in a regio-and stereoselective process to yield almost exclusively 2,4-pentadienoic esters with essentially (and in many cases exclusively) the 2E-stereochemistry.Keywords
