Abstract

Abstract O-Acetates of 4-hydroxy and 4-hydroxy-7-methoxy-2H-1, 4-benzoxazin-3-ones reacted with nucleophiles such as phenols, indoles and ethanethiol. The major reaction center is the positively-charged nitrogen atom. In the reaction with 2-methylindole, 6-position of the benzoxazinone ring is another major reaction center.
