Double C(sp³)–H Bond Functionalization Mediated by Sequential Hydride Shift/Cyclization Process: Diastereoselective Construction of Polyheterocycles

Abstract

Described herein are two novel types of double C(sp(3))-H bond functionalizations triggered by a sequential hydride shift/cyclization process: (1) construction of a bicyclo[3.2.2]nonane skeleton by a [1,6]- and [1,5]-hydride shift sequence and (2) sequential [1,4]- and [1,5]-hydride shift mediated construction of a linear tricyclic skeleton.
