Construction of Quaternary Stereocenters by Palladium-Catalyzed Carbopalladation-Initiated Cascade Reactions

The enantioselective synthesis of molecules containing quaternary stereocenters is a field of intense research interest and development. Among the known organic transformations, carbopalladation-initiated domino transformations constitutes a general method ...

Water as a Hydride Source in Palladium-Catalyzed Enantioselective Reductive Heck Reactions

Qian Wang, Jieping Zhu, Wangqing Kong

Pd-catalyzed intramolecular asymmetric carbopalladation of N-aryl acrylamides followed by reduction of C(sp3)-Pd intermediate using diboron–water as a hydride source afforded enantioenriched 3,3-disubstituted oxindoles in high yields and enantioselectiviti ...

Synthesis of Diversely Functionalized Oxindoles Enabled by Migratory Insertion of Isocyanide to a Transient σ-Alkylpalladium(II) Complex

Qian Wang, Jieping Zhu, Wangqing Kong

Palladium-catalyzed intramolecular carbopalladation of N-aryl acrylamides followed by migratory insertion of an isocyanide-coordinated C(sp3)-Pd intermediate afforded an alkylimidoyl-Pd(II) complex, which can be intercepted by a nucleophile, including hete ...

Palladium-Catalyzed Enantioselective Domino Heck/Intermolecular C–H Bond Functionalization: Development and Application to the Synthesis of (+)-Esermethole

Qian Wang, Jieping Zhu, Wangqing Kong

Intramolecular asymmetric carbopalladation of N-aryl acrylamides followed by intermolecular trapping of the resulting σ-C(sp3)−Pd complex by azoles afforded 3,3-disubstituted oxindoles in good yields with excellent enantioselectivities. Two C−C bonds were ...
