Abstract:

Asymmetric phase transfer catalysis is of great importance in organic synthesis, which is widely used in building chiral blocks. Till now the chiral phase transfer catalysts mainly derive from cinchona and Maruoka?s C2 -type quarternary ammonium salt, however, the utilization of asymmetric phase transfer catalysis is scarcely explored. First we applied the non-chiral phase transfer catalyst in the synthesis of some drugs and drug intermediates. Then we designed some new phase transfer catalysts according to E. J. Corey?s theory of designing the chiral phase transfer catalysts derived from cinchona and synthesized them, after which we explored their application in traditional phase transfer catalysis, then we explored some new phase transfer catalytic reactions with the new catalysts and applied them in the synthesis of chiral drugs and chiral drug intermediate
