Abstract

Abstract Triethylamine catalyzes the reaction of 2-hydroxybenzonitrile (1) with aryl isocyanates to form the corresponding carbamates 2a-c, as well as the cyclization of the latter compounds to either 4 [N-(N-arylcarbamoyl)-imino]-3-aryl-2H-1, 3-benzoxazin-2-ones 4a-c, or 4-arylamino-2H-1, 3-benzoxazin-2-ones 7a-c, depending on the reaction temperature. Under analogous conditions, the carbamates obtained from 1 and 2- ...
