摘要
The addition of triphenylphosphine oxide significantly enhanced the degree of asymmetric induction (up to 96% ee) in the chiral La-BINOL-complex-catalyzed epoxidation of enones using tert-butyl hydroperoxide as the oxidant. The new protocol is highly general and practical. (C) 1998 Elsevier Science Ltd. All rights reserved.
