Abstract

A unique feature of multifunctional asymmetric catalysts is described. Catalytic asymmetric Michael reaction of cyclic enones with Horner-Wadsworth-Emmons reagents proceeds efficiently by use of an aluminum-lithium-BINOL complex that is activated by an addition of alkali metal reagent. In addition,rare earth-3-hydroxymethyl-BINOL complexes promote asymmetric epoxidation of cis-enones to afford cis-epoxyketones. Both of these types of reactions are believed to be realized by a synergistic cooperation of two different metals in the complexes. (C) 2000 Elsevier Science B.V. All rights reserved.
