N-HYDROXYPYRIDINE-2-THIONE CARBAMATES. VI. FUNCTIONALIZATION OF CARBON RADICALS FORMED BY AMINIUM CATION RADICAL CYCLIZATIONS

A variety of reagents have been evaluated for trapping carbon radicals formed from aminium cation radical cyclizations.Rapid "self-trapping" of these radicals by their PTOC carbamate precursors requires highly reactive trapping agents.Synthetically useful

N-HYDROXYPYRIDINE-2-THIONE CARBAMATES. IV. A COMPARISON OF 5-EXO CYCLIZATIONS OF AN AMINYL RADICAL AND AN AMINIUM CATION RADICAL

Cyclizations of the N-butyl-4-pentenaminyl radical and the N-butyl-4-pentenaminium cation radical were studied.The radicals were produced in chain reactions from the same N-hydroxypyridine-2-thione carbamate precursors.Rate constants for cyclization of the aminyl radical and ring opening of the product thus formed at 50 deg C were determined.Cyclizations of the aminium cation radical, formed by protonation of the aminyl radical, were studied under a variety of conditions.

LEWIS ACID ACTIVATED AND CATALYZED CYCLIZATIONS OF AMINYL RADICALS FROM N-HYDROXYPYRIDINE-2-THIONE CARBAMATES

A variety of Lewis acids promote 5-exo cyclizations of δ,ε-unsaturated aminyl radicals produced from N-hydroxypyridine-2-thione carbamates under very mild conditions; catalysis was demonstrated in several cases.
