Radical Cyclization of Epoxyketones via a 1,5-Bun3Sn Group or a 1,5-H Atom Transfer
Kim, Sunggak,Koh, Jae Suk
, p. 1377 - 1378 (2007/10/02)
Radical cyclization of epoxyketones is initited by Bun3Sn radical addition to epoxyketones, followed by epoxide fragmentation, 1,5-H- or 1,5-Bun3Sn transfer, and cyclization.
