Lipase-catalyzed Knoevenagel condensation between α,β-unsaturated aldehydes and active methylene compounds

Abstract

Abstract A simple and efficient Knoevenagel condensation between α,β-unsaturated aldehydes and active methylene compounds is reported. Notably, this condensation can be catalyzed by PPL (lipase from porcine pancreas) with satisfied yields (49%–92%). Moreover, PPL induces moderate Z/E selectivity in the Knoevenagel condensation.
