Visible-light-induced N-heterocyclic carbene mediated cascade transformation of N-alkenoxypyridinium salts
文献摘要：
While N-alkenoxypyridinium salts are widely used for the synthesis of α-functionalized ketones via umpolung strategy,such approaches are usually limited to special nucleophiles at high temperatures.Herein,we developed an alternative photoinduced N-heterocyclic carbene(NHC)-mediated functional-ization of N-alkenoxypyridinium salts with various nucleophiles,including tetramethylammonium azide,secondary amines,aryl and alkyl thiols,and even the challenging C(sp3)-nucleophiles,under mild con-ditions.A cascade radical-radical coupling/nucleophilic substitution sequence was proposed,wherein the NHC enabled the formation of a photoactive electron donor-acceptor complex for α-iodo ketone synthe-sis.
