Time-Economical Radical Cascade Cyclization/Haloazidation of 1,6-Enynes: Construction of Highly Functional Succinimide Derivatives.

A "time-economical" radical cascade cyclization/haloazidation of 1,6-enynes provides a direct approach to access highly functional succinimide compounds. Moderate to excellent yields along with excellent Z/E ratio were obtained under the reaction features of broad substrate scope, good functional group tolerance, and mild reaction conditions.
