Modular Synthesis of Benzocyclobutenes via Pd(II)-Catalyzed Oxidative [2+2] Annulation of Arylboronic Acids with Alkenes

Qian Wang, Jieping Zhu, Takuji Fujii, Simone Gallarati

Benzocyclobutenes (BCBs) are highly valuable compounds in organic synthesis, medicinal chemistry, and materials science. However, catalytic modular synthesis of functionalized BCBs from easily accessible starting materials remains limited. We report herein ...

Palladium Catalysed Intramolecular Carbo-oxygenation of Propargylic Amines to Access 1,2-Amino Alcohols and alpha-Amino Ketones via in situ Tether Formation

Phillip Gulliver Dominic Greenwood

a-Amino ketones and 1,2-amino alcohols are important structural motifs in organic chemistry, that can be observed in natural products, pharmaceutically and bioactive compounds. For these reasons, they constitute privileged targets for the development of ne ...

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 ...

Palladium-Catalyzed Enantioselective Narasaka-Heck Reaction/Direct C−H Alkylation of Arenes: Iminoarylation of Alkenes

Qian Wang, Jieping Zhu, Xu Bao

A palladium-catalyzed reaction of g,d-unsaturated oxime esters with oxadiazoles afforded dihydropyrroles in good to excellent yields through an intramolecular iminopalladation/intermolecular direct heteroarene C-H alkylation cascade. This unprecedented imi ...

α-Oxo-Ketenimines from Isocyanides and α-Haloketones: Synthesis and Divergent Reactivity

Qian Wang, Jieping Zhu, Mathias Mamboury

The palladium-catalyzed reaction of a-haloketones with isocyanides afforded -oxo-ketenimines through alpha-hydride elimination of the beta-oxo-imidoyl palladium intermediates. Reaction of these relatively stable alpha-oxo ketenimines with nucleophiles suc ...

Divergent Access to (1,1) and (1,2)-Azidolactones from Alkenes using Hypervalent Iodine Reagents

Jérôme Waser, Stefano Nicolai, Franck Le Vaillant, Thibaut Christian Courant, Sébastien Pierre Louis Alazet

A versatile synthesis of azidolactones through azidation and cyclization of carboxylic acids onto alkenes has been developed. Based on either photoredox or palladium catalysis, (1,1) and (1,2) azido lactones can be selectively synthesized. The choice of ca ...
