摘要: Phase-transfer catalysis has been recognized as a powerful and green sustainable method for organic synthesis in both industry academia. Since the pioneering studies on enantioselective phase-transfer reactions promoted by cinchona alkaloid-derived tetraalkylammonium salt catalysts, this research field served an attractive area pursuit of chemistry. Although various types chiral quaternary ammonium salts have developed highly selective asymmetric last three decades, examples phosphonium onium catalysts are limited, effective relatively recent years. This review summarizes development related environmentally benign transformations.
