Introduction of 90-39-1 :

(-)-Sparteine ((-)-Lupinidine) is a chiral proton base and catalytic promoter. (-)-Sparteine promotes the enantioselective carbolithiation of cinnamyl derivatives with primary and secondary organolithium reagents. (-)-Sparteine forms mixed aggregates with lithium halides. As an exogenous chiral base, (-)-Sparteine deprotonates palladium-bound secondary alcohols, promotes the formation of palladium-alkoxide species, and alters the rate-limiting step of the catalytic cycle, thereby affecting reaction rate and enantioselectivity[1][2]. In Vitro:(-)-Sparteine promotes the enantioselective carbolithiation of various cinnamyl derivatives (including alcohol, ether, amine and homoallylic alcohol derivatives) with primary and secondary alkyllithiums[1].
