摘要

A new class of compounds, 2-alkylidene-benzo [1, 3] dioxin-4-ones, have been synthesised by cyclisation of the corresponding o-acyloxy benzoyl chlorides with triethylamine. The 2- methylene-benzo [1, 3] dioxin-4-one acts as a prodrug for aspirin and is a useful intermediate in the synthesis of new aspirin prodrugs.
