Lv. Jackson et Jc. Walton, Generation of aminoacyl radicals from 1-carbamoyl-1-methylcyclohexa-2,5-dienes: a new tin-free homolytic route to beta- and gamma-lactams, PHYS CHEM P, 2(23), 2000, pp. 2327-2328
Radical induced homolyses of 1-carbamoyl-1-methylcyclohexa-2,5-dienes took
place cleanly to yield aminoacyl radicals, with no competition from the alt
ernative dissociation to methyl radicals: beta- and gamma -lactams were obt
ained from ring closures of suitably unsaturated model compounds.
