- 論文の詳細を見る
Benzoxazole and o-aminophenol each reacted with dimethyl acetylenedicarboxylate (DMAD) to give the same product, which was previously suggested to be a [1,4] benzoxazine [2,3-b] pyran derivative (2). An X-ray crystallographic analysis has now shown the structure of this compound to be trimethyl 2,3-dihydro-2-oxo-4H-1,4-benzoxazine-△^<3.7>-aconitate. A similar treatment of o-aminophenols and β-aminoalcohols with an excess of DMAD afforded new 1,4-benzoxazines and 1,4-oxazines, respectively.
