We recently reported an intramolecular version of the Schmidt reaction'in which hydrazoic acid was replaced by an alkyl azide connected to the reactive ketone. 2 This is an unusual example of intramolecularity because the analogous H+-promoted intermolecular reaction does not succeed at alL3 Given the potential utility of a general method for the intermolecular insertion of an N-alkyl group adjacent to a ketone, other conditions to effect ...
