Interrupted Cross Coupling

印第安纳大学化学系
Stereospecific cross-coupling of chiral alkyl metal intermediates is a recognized challenge in modern organic synthesis. Here an alternative strategy is presented in which a chiral alkyl metal is generated as a catalytic intermediate by boryl-metalation of an alkene followed by cross coupling. This interrupted cross coupling represents an attractive approach in chemical synthesis because two new bonds and two new stereocenters are generated in a single operation. In addition, due to the synthetic versatility of the carbon-boron bond, a variety of structures can be readily prepared, thus representing a general approach toward carbofunctionalization of alkenes. The scope, mechanistic details, and application to complex molecule synthesis will be discussed.
