The cinchona alkaloid dimer (DHQD)2 PHAL has been shown to be a broadly applicable catalyst for asymmetric halogenations. However, this catalyst does not have to be dimeric and a class of monomeric quinidine and quinine-derived catalysts was prepared, often showing

商品

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.
