Heteroatom-Tethered ω-Alkenylallylboronates: Stereoselective Synthesis of Heterocyclic Derived Alcohols

Abstract The synthesis of ω-alkenylallylboronates using a heteroatom tether to join both functional groups is described for the first time. Then, these unprecedented compounds were used in tandem Brønsted acid catalyzed allylboration/ring-closing metathesis (RCM) reaction affording heterocyclic derived alcohols as single diastereoisomers. low enantioselectivity observed asymmetric version chiral phosphoric catalyst was studied theoretically.
