developed for the general synthesis of dinitrile-substituted cyclopropanes in moderate to excellent yields. A variety of 2-arylacetonitriles and α-bromoennitriles were compatible under the standard conditions. The reaction was achieved through tandem Michael-type addition followed by intramolecular cyclization. The preliminary application of this method was confirmed by the synthesis of the 2,4-dioxo-3-azabicyclo[3
已经开发了一种方便有效的环化反应,用于以中等至优异的产率合成二腈取代的环丙烷。多种 2-芳基乙腈和 α-溴腈在标准条件下是相容的。该反应是通过串联迈克尔型加成,然后是分子内环化来实现的。2,4-二氧代-3-氮杂双环[3.1.0]己烷支架的合成证实了该方法的初步应用。
