has been developed for the precise construction of enantioenriched azaspiro polycyclic scaffolds. Structurally diverse azaspiro polycycles bearing multiple contiguous stereocenters are obtained with excellent results (up to 99:1 e.r., >95:5 d.r.) via sequential enantioselective four-component Ugi reactions/post-Ugi transformations with substrates containing prerequisite functional groups in the presence
已经开发出一种用于精确构建对映体富集的氮杂螺多环支架的特权策略。通过连续对映选择性四组分 Ugi 反应/后 Ugi 转化,在存在以下物质的情况下,使用含有必要官能团的底物,获得结构多样的带有多个连续立构中心的氮杂螺多环,并获得优异的结果(高达 99:1 er,>95:5 dr)阴离子立构-
