Sodium carbonate promoted [3 + 2] annulation of α-halohydroxamates and isocyanates†
Abstract
A new [3 + 2] annulation of readily available α-halohydroxamates and isocyanates has been developed. This protocol allows a rapid assembly of various hydantoins in good to high yields as well as a broad substrate scope and good functional group tolerance.
