(3-Bromoalken-1-yl)dialkylboranes, generated by hydroboration of propargyl bromide with dialkylboranes, smoothly rearranges to (E)-allylic boranes which can be trapped with aldehydes. The resulting one-pot three-component sequence represents a route to anti-homoallylic alcohols in fairly good yields. (C) 1998 Published by Elsevier Science Ltd. All rights reserved.
