Enantioselective Palladium-Catalyzed Allylic Substitution of Sodium Benzotriazolide

Chiral allylic benzotriazole-containing regioisomers 4 and 5 were synthesized by enantioselective palladium-catalyzed allylation of sodium benzotriazolide with a range of allylic carbonates in 50–89 % yields, regioselectivities of 2.2:1 to 1:3.4, and ee values of up to 95 %.
