been devised to furnish densely functionalized 3‐hydroxyindanone scaffolds in high yields with excellent diastereoselectivity. Unlike preceding approaches that account for the formation of the pentanoid ring, this strategy features construction of the aromatic ring. The protocol is scalable, displays very broad substrates scope including late‐stage functionalization of bioactive estrone, applicable
已设计出碱促进的亚烷基丙二腈与环戊烯-1,3-二酮的乙烯基级联反应,以及随后的还原顺序,以高产率提供具有出色的非对映选择性的致密官能化的3-羟基茚满酮骨架。与前述解决戊二烯环形成的方法不同,该策略的特征在于芳香环的构建。该协议是可扩展的,显示了非常广泛的底物范围,包括生物活性雌酮的后期功能化,适用于活化的香豆素系统,并且适合于使用茚并喹啉衍生物。
