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 yi
The reactions of acylsilanes with KCN under liquid-liquid phase-transfer catalytic conditions proceeded smoothly via the Brook rearrangement to produce O-silylated cyanohydrin derivatives in excellent yields. We also found that ฮฑ-cyano carbanions generated by the Brook rearrangement in the reaction
