Abstract

Abstract Stereoselective preparation of a variety of synthetically useful functionalized bicyclo [5.3. 0] decane derivatives was achieved by tandem cyclization of 3-siloxy-1, 3, 9-triene-7- yne derivatives based on the electrophilic activation of alkynes catalyzed by [W (CO) 5 (L)]. The reaction proceeded smoothly under photoirradiation, and various substrates were cyclized to give the corresponding bicyclic compounds with up to four chiral centers ...
