摘要

Organotin hydride induced intramolecular radical cyclization reactions are now widely used for the construction of fused carbo-and heterocyclic ring systems.'With only a few exceptions, 5-exo-trig radical cyclizations are generally preferred over 6-endo-trig ring closures in substituted hexenyl systems. In contrast to the alkyl radical reactions in organic synthesis, only limited information is available on the rates and regiochemistry of aryl radical ring ...
