Abstract
Regio- and stereoselective 1,4-addition of borylstannane 2 to 1,3-dien es smoothly proceeds in the presence of catalytic amounts of Pd-2(dba) (3) and P(OCH2)(3)CEt, giving high yields of (Z)-1-boryI-4-stannyI-2-b utenes 3. The reaction of 3 with aldehyde provides a facile method for preparing various homoallyl alcohols. (C) 1998 Elsevier Science Ltd. All rights reserved.
