Abstract

A series of fifteen new N-pyridyl-3,6-dihydro-1,2-oxazines has been prepared from 1,3-butadienes and nitrosopyridines. 2-Aminopyridine, 2-amino-4-methyipyridine and 2-amino-6-methylpyridine were converted via nitroso compounds to 1,2-oxazines. The transformation was carried out sequentiaily in one vessel without isolation of either the intermediate suifilimine or the nitroso compound.
