The asymmetrical epoxidation catalytic converter of the enones and production manner null of the optical active epoxide which uses

摘要

PROBLEM TO BE SOLVED: To obtain a catalyst for the asymmetric epoxidation of enones giving high reactivity, high yield and high optical purity. ;SOLUTION: The catalyst used in the asymmetric epoxidation of enones contains (R)-binaphthol, lanthanum triisoproxide and lutidine-N-oxide, 1,3- dimethyl-2-imidazolidinedione, hexamethylphosphoroustriamide, triphenylphosphine oxide, tri(2-methylphenyl)phosphine oxide or tri(4- methylphenyl)phosphine oxide.;COPYRIGHT: (C)2000,JPO
