| Abstract: | A method for direct asymmetric chlorination of aldehydes and 2,3,4,5,6,6-hexachloro-2,4-cyclohexadien-1-one catalyzed by Pro-Trp in the presence of N-methylmorpholine (NMM) and ionic liquid ZnCO(NH2)2]3Cl2 has been developed. This method produces the corresponding optically active chlorinated products with high yields (up to 95%) and good enantioselectivities (up to 92%ee). The approach has advantages in simple isolation and reusablility of catalyst and ionic liquids. |
