reactivity of cyclic β-dicarbonyls (cyclic β-diketones, 4-hydroxy-2(5H)-furanones, and Meldrum‘s acids) towards metal/hydroperoxide system was disclosed. An efficient method for the peroxidation of 4-hydroxy-2(5H)-furanones and Meldrum's acids with TBHP has been developed using Co2+ salt as a catalyst. Cycle cleavage, expected from previous reports for cyclic β-dicarbonyls, was observed only for cyclic 1,3-diketones
公开了环状β-二羰基(环状β-二酮、4-羟基-2(5H)-呋喃酮和Meldrum酸)对金属/氢过氧化物体系的反应性。使用Co 2+盐作为催化剂,开发了一种用TBHP过氧化4-羟基-2(5 H )-呋喃酮和Meldrum 酸的有效方法。根据之前关于环状 β-二羰基的报告预期,仅在环状 1,3-二酮中观察到了循环裂解。总体而言,这项工作将金属催化过氧化的理解扩展到不同的结构主题。
