Studies on 1,3-Benzoxazines. I. Synthesis of Primary 2-Amino-pyridines via the Reaction of Imidoyl Chlorides of 1,3-Benzoxazines with Pyridine N-Oxides

A new synthetic method for primary 2-aminopyridine derivatives is described.Treatment of the imidoyl chlorides of 1,3-benzoxazines (1a-i) with pyridine N-oxides resulted in the introduction of an oxazine moiety into the α-position of the pyridine ring through rearrangement of the initially formed reaction adduct.Acid hydrolysis of the rearrangement products afforded 2-aminopyridine derivatives in excellent yields.When methoxypyridine N-oxides were used, products of a different type (10 and 14) were obtained.
