In this paper,a concise protocol for synthesis of possess potential pharmacological active amide class heterocyclic ketene aminals(HKAs) has been developed,which based on the six or seven-membered HKAs 1~2,using aryl isocyanate 4 as acylation agent.The regioselective acylation reaction of HKAs in 1,4-dioxane at room temperature gave compounds 5~6 with 90%~98% yields.However,the five-membered HKAs 3 and aryl isocyanate 4 reacted in 1,4-dioxane catalyzed by Cs2CO3 at room temperature to obtain compounds 7 in 78%~93% yields.

Key words: heterocyclic ketene aminals, isocyanate, regioselective, acylation reaction
