Enantioselective nickel/phosphine-catalyzed reductive Coupling of alkynes and aldehydes provides rapid access to synthetically useful allylic alcohols with high enantiomeric excess. A related reaction involving epoxides is enantiospecific, transforming alkynes and chiral terminal epoxides into enantiomerically pure homoallylic alcohols containing a trisubstituted olefin of defined geometry. A gram-scale example of each of these processes is described. (C) 2003 Elsevier Ltd. All rights reserved.
