Mp. Cooke et D. Gopal, STEREOSELECTIVE CONSTRUCTION OF FUNCTIONALIZED BICYCLIC CARBOCYCLES THROUGH METAL-HALOGEN EXCHANGE-INITIATED SEQUENTIAL CONJUGATE ADDITION-REACTIONS, Tetrahedron letters, 35(18), 1994, pp. 2837-2840
Rapid metal-halogen exchange reactions have been used to initiate the
stereoselective formation of trans-bicyclo[4.3.0]nonane and strained t
rans-bicyclo[3.3.0]octane derivatives through sequential intramolecula
r conjugate addition reactions. Stereoselectivity has been controlled
in anionic olefin addition reactions as well as in corresponding radic
al cyclizations through control of acceptor olefin stereochemistry.
