Abstract

0022-3263/87/1952-1624 $01.50/O where aluminum enolate intermediates generated by the hydralumination of a,@-unsaturated carbonyl compounds by DIBAH are invo1ved. l In the present study, we tried to extend the scope of this novel reducing reagent; ie, we investigated the conjugate reduction of a,@-acetylenic ketones and esters by the DIBAH- HMPA and the MeCu-DIBAH-HMPA systems (eq 1). Although catalytic
