摘要

Abstract: Oxidation of anthranilamides, salicylamides and some b-substituted amides with iodobenzene diacetate in methanolic potassium hydroxide led to a new and convenient synthesis of 2-benzimidazolones, 2-benzoxazolones and related compounds, respectively. The reaction probably occurs via initial Hofmann-type rearrangement followed by intramolecular cyclization of intermediate isocyanate. Key words: hypervalent iodine, 2- ...
