Abstract: Stereo- and enantioselective syntheses of 1,2-oxaborinan-3-enes and δ-boryl-substituted homoallylic alcohols are reported. We developed a practical approach to synthesize α-boryl-substituted allylboronate. This reagent was utilized to generate α,α-disubstituted allylboronates, and such reagents cannot be accessed… read more here.
