A new type of catalysis by copper(I) salts in the Barbier-type aldehyde allylation with tin(II) chloride. Short syntheses of (±)-lavandulol and its γ, δ-dihydro derivative
Abstract
Copper(I) halides and cyanide catalyse the Barbier-type aldehyde allylation with allylation with allylic bromides, chlorides or sulfonates and tin(II) chloride enabling the reaction to take place under very mild conditions with high efficiency.
