dcterms:description
This paper describes our work concerning the preparation of novel benzoxazinones substituted with indole moiety or acyl in position 2. Their preparation is achieved by cyclodehydration of the appropriate N-acylanthranilic acids by means of acetic anhydride or thionyl chloride, which is consistent with the standard procedure. In addition, a new route to starting N-acylanthranilic acids has been established. Firstly, N-(α-ketoacyl)anthranilic acids were readily obtained from 4-hydroxyquinolin-2-ones by two-step oxidation including peracetic acid hydroxylation into the corresponding 3-hydroxyquinoline-2,4-diones and subsequent oxidative ring opening with periodic acid or sodium periodate. In the cases of the preparation of the mentioned indole derivatives, the appropriate transformations of α-ketoacyl chain were carried out by known chemistry. As a part of our continued interest in the reactivity of various heterocyclic systems, we have studied reactions of title compounds with some nucleophiles. All compounds under investigation were characterized by available methods of structural analysis including high resolution mass spectrometry and two-dimensional NMR techniques.
