Hydrogen??Bond??Promoted Palladium Catalysis: Allylic Alkylation of Indoles with Unsymmetrical 1, 3??Disubstituted Allyl Acetates Using Chiral Bis (sulfoxide) …
The palladium-catalyzed asymmetric allylic alkylation (AAA, Tsuji–Trost reaction) is a powerful strategy for construction of carbon–carbon (CÀC) and carbon–heteroatom (CÀX) bonds.[1] Various ligands, such as monodentate phosphines, bidentate N, N-, P, N-, P, P- ligands, etc., have been used in this reaction, especially for symmetric 1, 3-disubstituted allylic substrates.[1g, 2] To date, asymmetric alkylation (CÀC bond formation) of racemic, ...
