A highly efficient domino Michael addition–alkylation reaction of 1,3-dicarbonyl derivatives with 2-nitroacrylates was developed in water. The procedure tolerates a series of functional groups such as methoxy, bromo, chloro, and heteroaromatic groups, providing three types of 2,3-dihydrofuran derivatives in moderate to good yields.
在水中开发了一种高效的多米诺迈克尔加成-烷基化反应,通过1,3-二酮衍生物与2-硝基丙烯酸酯反应。该方法对一系列功能团(如甲氧基、溴、氯和杂环芳香族基团)具有良好的耐受性,提供了三种类型的2,3-二氢呋喃衍生物,产率中等至良好。
