A tandem Michael addition–cyclization of nitroalkenes with 1,3-dicarbonyl compounds was developed using phase transfer catalyst (PTC), allowing for the synthesis of polysubstituted-[4,5]-dihydrofuran in high yields. A wide range of substrates were demonstrated by this one-step process. Meanwhile, nitro group was substituted to form corresponding nitrite ion detected in the aqueous phase providing a
使用相转移催化剂 (PTC) 开发了硝基烯烃与 1,3-二羰基化合物的串联迈克尔加成环化,允许以高产率合成多取代-[4,5]-二氢呋喃。这种一步法展示了广泛的基材。同时,硝基被取代形成相应的亚硝酸根离子,在水相中检测到,为有毒和爆炸性含硝基化合物的脱硝提供了合理的途径。我们的 DFT 计算也支持了所提出的机制。
