fused carbocycles is a key challenge in synthetic chemistry. Herein, an unprecedented and practical tandem Nazarov/oxidative umpolung 4π-ring closure of readily available 1,2-allenyl aryl ketones mediated by iron(III) chloride has been developed, furnishing a new family of indanone-fused molecular architectures in moderate to excellent yields. The indanone-containing blocks can be efficiently converted
三维熔融碳环的快速构建是合成化学中的关键挑战。在此,已开发出一种空前的,实用的串联Nazarov /氧化mpolung4π环封闭由氯化铁(III)介导的易于获得的1,2-烯基芳基酮的化合物,为中度至优异的茚满酮稠合分子结构家族提供了新的家族。产量。含茚满酮的嵌段可以有效地转化为不对称的二苯并[ a,e ]戊烯。重要的是,已经实现了多样化的合成应用以提供密集功能化的多环阵列。
