Abstract

Abstract A series of 3-substituted 3, 4-dihydro-1H-2, 3-benzoxazin-1-ones (IV)(Scheme I) was prepared by reaction of 2-bromomethylbenzoyl chlorides (II) with N- hydroxyethylcarbamate (III) or with benzohydroxamic acids. Acid hydrolysis of 3-carbethoxy (IVa) and 3-benzoyl derivatives (IVb) afforded a mixture of 2-(hydroxyaminomethyl) benzoic acid (V) and 2, 3-dihydro-2-hydroxy-1H-1-isoindolinone (VII). Compound IVa reacted with ...
