Ni-catalyzed highly regioselective carboborylation bifunctionalization of allenes: access to α-substituted-γ-boro-δ-enoates†

Abstract

A Ni-catalyzed highly regioselective carboborylation bifunctionalization of allenes was developed, and a series of α-substituted-γ-boro-δ-enoates were generated in good to high yields. This reaction has the advantages of mild reaction conditions, a wide substrate scope and good late-stage modification applications, providing a new strategy for the synthesis of configurationally defined trisubstituted vinyl boron compounds.
