Abstract
It has been shown that the condensation of tertiary aminophenylcarbinols with 2-hydroxybenz(naphth)aldehydes gives the corresponding 1,2-dihydrobenzoxazines and their structural Schiff base isomers. The reaction of 2-[2-hydroxyphenyl(naphthyl)]-1,2-dihydro-4H-3,1-benzoxazines with aliphatic aldehydes gives substituted 3,1-benzoxazino[1,2-c][1,3]benz(naphth)oxazines.
