Abstract

The copper/di-tert-butyl peroxide-catalyzed regioselective hydroxyphosphorylation of 1,3-enynes is described. The advantages of the reported radical reactions are excellent functional group tolerance, the use of a catalytic amount of copper and di-tert-butyl peroxide ( t BuOO t Bu) as a radical initiator, and mild reaction conditions. The desired products are obtained in moderate to excellent yields after purification.
