A stereoselective [3+2] cycloaddition approach to functionalized pentaquinanes starting from cis-syn-cis triquinanes, derived from Cookson's diones, is reported. The side view of pentaquinane crystal structure resembles a flying camera drone, hence the name ‘pentaquinadrone’ is given. This transformation involves in generation of six new stereocenters in a single step.
报道了一种从库克森二酮衍生的顺-顺-顺三喹烷开始的功能化五醌的立体选择性 [3+2] 环加成方法。五
喹啉晶体结构的侧视图类似于飞行的相机无人机,因此命名为“五
喹啉”。这种转变涉及在一个步骤中生成六个新的立体中心。
