中文摘要	In this paper, chiral molybdenum(VI) or tungsten(VI) 2'-pyridinyl alcoholate complex catalyzed asymmetric epoxidation of cis-1-propenylphosphonic acid in H2O was reported. This is an asymmetric epoxidation reaction taking place on the solid-liquid interface. The highest ee value of 71% was achieved by using chiral molybdenum(VI) 2'-pyridingyl alcoholate complex at 0 V. After addition of phase transfer catalyst Bu4NBr, the yield and ee value were remarkably increased. For example, using chiral tungsten(VI) 2'-pyridinyl alcoholate complex at 50 V, the ee value was increased from 54% to 78%.
