Jm. Duffault et F. Tellier, A NEW ROUTE TO THE SYNTHESIS OF BICYCLO[3.3.2]NONENE BY RADICAL CYCLIZATION, Synthetic communications, 28(13), 1998, pp. 2467-2481
Radical-induced cyclisation to form 7-membered ring with bicyclic fram
ework was achieved by tributyltin hydride (TBTH) and alpha, alpha'-azo
bis-(isobutyronitrile) (AIBN).
