W(CO)_5(L)-Catalyzed Tandem Intramolecular Cyclopropanation/Cope Rearrangement for the Stereoselective Construction of Bicyclo[5.3.0]decane Framework

摘要

In this paper,we report a facile method for the stereoselective construction of the bicyclo[5.3.0]decane skeleton from 3-siloxy-1,3,9-trien-7-ynes through divinylcyclopropane intermediates based on the W(CO)_5(L)-catalyzed electrophilic activation of alkynes as a biscarbene equivalent.
