The title radical precursors (PTOC carbamates) were employed as sources of a variety of 5,6-unsaturated aminium cation radicals. 5-Exo radicalcyclization followed by trapping by t-BuSH or the PTOC carbamate gave a variety of aklaloid skeletons, typically in good to excellent yields, including pyrrolidines, perhydroindoles, pyrrolizidines, tropanes, 9-azabicyclo[4.2.1]nonanes, 6-azabicyclo [3.2.1]octanes

Dithiocarbamate-substituted lactams, prepared through group-transfer cyclizationreactions of carbamoylradicals, undergo a Chugaev-like thermal elimination of the dithiocarbamategroup in refluxing diphenyl ether to form alpha,beta- and/or beta,gamma-unsaturated amides, depending on the structure of the starting material. This reaction sequence was used to prepare an unsaturated [3.2.2] bridged bicyclic
