Abstract

The hydroboration of alkenes represents a versatile synthetic method for the functionalization of organic compounds.[1] The installed carbon–boron bond can be converted into CÀO, CÀ N, and CÀC bonds with retention of stereochemistry.[1b] Several highly enantioselective catalysts have been developed by the groups of Hayashi,[2] Brown,[3] Knochel,[4] Togni,[5] and Takacs [6] among others, allowing the hydroboration ...
