Palladium-Catalyzed Modular and Enantioselective cis-Difunctionalization of 1,3-Enynes with Imines and Boronic Reagents

Here we report that a palladium(0) complex can mediate the unprecedented intermolecular coupling reaction of 1,3-enynes and N-sulfonylimines regio- and stereoselectively, and the resultant palladium(II) species undergo a cascade Suzuki reaction with organ

Regioselective Access to 3-Ethylideneflavanones via Rhodium(I)-Catalyzed 1,3-Enyne Hydroacylation/Annulation Cascades

The highly efficient synthesis of 3-ethylideneflavanones through sequential rhodium(I)-catalyzed hydroacylation of terminal aryl-substituted 1,3-enynes with chelating aldehydes and annulation is described. This straightforward protocol highlights an unprecedented C3-regioselective hydroacylation of 1,3-enynes, excellent functional group compatibility, and complete atom economy. (Figure presented.).

Preparation of Chiral Allenes through Pd-Catalyzed Intermolecular Hydroamination of Conjugated Enynes: Enantioselective Synthesis Enabled by Catalyst Design

In this study, we establish that conjugated enynes undergo selective 1,4-hydroamination under Pd catalysis to deliver chiral allenes with pendant allylic amines. Several primary and secondary aliphatic and aryl-substituted amines couple with a wide range of mono- and disubstituted enynes in a nonenantioselective reaction where DPEphos serves as the ligand for Pd. Benzophenone imine acts as an ammonia surrogate to afford primary amines in a two-step/one-pot process. Examination of chiral catalysts revealed a high degree of reversibility in the C-N bond formation that negatively impacted enantioselectivity. Consequently, an electron-poor ferrocenyl-PHOX ligand was developed to enable efficient and enantioselective enyne hydroamination.
