Abstract

The preparation of m-benzoxazines by reaction of formaldehyde and primary amines with phenols,'polyhydr~ xybenzenes,~~~ or naphthols4 has been extensively investigated by Burke and co-workers. Their recent paper3 concerned with the synthesis of bisoxazines5 I and I1 (equation I), by the condensation of hydroquinone, formaldehyde, and a primary amine in a molar ratio of 1: 4: 2, prompts this disclosure of our independent investigations ...
