A novel triborylmethane reagent was successfully synthesized, which reacted with aldehydes under the condition of pentamethyldiethylenetriamine (PMDETA) as additive, enabling the synthesis of dissymmetrical gem-diborylalkenes. The method exhibits excellent stereoselectivity and good yields. The reaction has good substrate compatibility and the two boryl moieties in the product have different reactivities. Through cross-coupling with aryl halides, the Bpin moiety can be converted into an aryl group, achieving the stereoselective synthesis of trisubstituted vinylboronates.
Key words: gem-diborylalkenes; B—O elimination; boron reagent; aldehydes
