Reductive Cyclization of Carbon-Centered Glycine Radicals; A Novel Synthetic Route to Cyclic α-Amino Acids

Esch, Peter M.,Hiemstra, Henk,Boer, Richard F. de,Speckamp, W. Nico

, p. 4659 - 4676 (2007/10/02)

Reductive cyclizations (tributyltin hydride, AIBN) of several α-(phenylthio)glycine derivatives with a 3-alkenyl substituent at nitrogen are reported.These reactions proceed via 2-aza-5-alken-1-yl radicals as intermediates which bear electron-withdrawing
