Trost, Barry M.; Frederiksen, Mathias U. published the artcile< Palladium-catalyzed asymmetric allylation of prochiral nucleophiles: synthesis of 3-allyl-3-aryl oxindoles>, HPLC of Formula: 152140-65-3, the main research area is arylindolinone allyl acetate allylation palladium chiral phosphine; allyl arylindolinone asym preparation; palladium chiral phosphine asym allylation catalyst.
Excellent yields and enantioselectivies were attained in the synthesis of 3-alkyl-3-aryloxindoles, e.g., I, based on the Pd-catalyzed asym. allylic alkylation reaction. This approach utilizes a nonbasic hydroxylic additive in the transformation of 3-aryloxindoles into complex, synthetically valuable oxindoles.
Angewandte Chemie, International Edition published new progress about Allylation catalysts. 152140-65-3 belongs to class chiral-phosphine-ligands, and the molecular formula is C54H42N2O2P2, HPLC of Formula: 152140-65-3.
