Abstract
2-Methyl[3,1]benzoxazin-4-one ( I ) is easily accessible , but its chemistry has not been investigated enough. Structure similarity between I and phthalic anhydride encouraged us to investigate the reaction of I with compounds bearing active methylenes namely diethyl malonate, ethyl acetoacetate and acetylacetone in presence of zinc chloride, Thus new compounds II, III and IV were synthesized. Those compounds were used as precursors for the synthesis of various spiroheterocycles.
