A new asymmetric synthesis of chiral organo halides from the corresponding racemic alcohols through stereo retention from an enantiomer and inversion for the other one was investigated. Initial study using enantiomerically pure phenethyl alcohol and various amine nucleophiles revealed that the enantioselectivities largely depended on the structure of the amine nucleophiles, suggesting that the present approach can be a potent new methodology for asymmetric halogenation of alcohols.We tested various chiral organocatalysts and found that some chiral pyridine and phosphine based organocatalysts showed moderate enantioselectivities for the chlorination of racemic alcohols.
