✦ Synopsis

The catalytic asymmetric Darzens condensation promoted by the quaternary ammonium salt (PTC A) derived from cinchonine as a phase-transfer catalyst is described. Treatment of phenacyl chloride with various aldehydes under mild reaction conditions afforded the corresponding desired product in good yield with good to moderate enantiomeric excess.
