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.
通过用三乙胺环化相应的邻-酰氧基苯甲酰氯,已经合成了新的一类化合物2-亚烷基-苯并[1,3]二恶英-4-酮。2-亚甲基-苯并[1,3]二恶英-4-酮用作阿司匹林的前药,并且在合成新的阿司匹林前药中是有用的中间体。
