Hydrazones of ketones, 1, are transformed into 1-chloroalkylazo compounds, 2, which react with Lewis acids to give transient 1-aza-2-azoniaallene salts, 3.The cations 3 react with acetylenes, olefins, isocyanates, carbodiimides, and nitriles under -c
One-pot cyclizations of dilithiated oximes and hydrazones with epibromohydrin. Efficient synthesis of 6-hydroxymethyl-5,6-dihydro-4H-1,2- oxazines and oxazolo[3,4-b]pyridazin-7-ones

The one-pot cyclization of dilithiated oximes with epibromohydrin provided a convenient and regioselective approach to 6-hydroxymethyl-5,6-dihydro-4H-1,2- oxazines. The reaction of the latter with phosphorus tribromide resulted in a Beckmann rearrangement
