Maruoka catalysts enable enantioselective preparation of α-amino acids from glycine derivatives via asymmetric phase transfer catalysis.
不对称相转移催化（PTC）已被公认为是许多均相合成有机转化的“绿色”替代方法，并且已被广泛应用。合成修饰的金鸡纳生物碱是用于不对称PTC的典型手性有机催化剂。
Asymmetric phase-transfer catalysis (PTC) has been recognized as a “green” alternative to many homogeneous synthetic organic transformations, and has found widespread application. Synthetically modified cinchona alkaloids are typical chiral organocatalysts used in asymmetric PTC.
