N-chlorocarbamate = nitrene

Posted by naturalproductman on October 14, 2011

Carl Lovely and colleague at UT Arlington have reported in Organic Letters on the use of an N-chlorocarbamate reagent that is basically the equivalent of a nitrene.  Interestingly they use an imidazolinium substrate – that we usually see in the benzoin condensations – and reacts with the N-chlorocarbamate reagent to form the new C-N double bond.
