Abstract:
A series of highly functionalized 1,4-dihydropyridines was synthesized via one-pot multicomponent reactions of aromatic aldehyde, malononitrile and N-methyl-1-(methylthio)-2-nitroethenamine using Porcine pancreatic lipase(PPL) as catalyst in DMSO. This protocol is featured by mild reaction conditions, simple operation and environmental acceptability.
