✦ Synopsis
Asymmetric phase-transfer catalysis (PTC) reactions constitute one of the most challenging fields of contemporary organic synthesis. [1] Following the seminal work by ODonnell et al. [2a] and Grabowski et al. [2b] dramatic improvements in the asymmetric efficiency of PTC reactions were achieved by introducing (9-anthracenylmethyl)cinchonidinium (1 a, R allyl, benzyl, H) and other cinchoninium salts as catalysts
