Synthesis of Allylboronates via Zweifel‐type Deprotonative Olefination.

A method for the synthesis of allylboronates via Zweifel‐type deprotonative olefination was demonstrated. Tetrasubstituted vinylboronates were used as the substrates. NCS (N‐chlorosuccinimide) was used as a bifunctional additive, electrophile and base. This method exhibited a different elimination strategy in Zweifel type transformation to afford allylboronates. The homo‐alcohols and alkenes were stereoselective synthesized from the obtained allylboronates, demonstrating the synthetic value of this methodology. [ABSTRACT FROM AUTHOR]
