Article Abstract

A highly efficient approach to indolo [1,2-a]quinoxaline derivatives through a Pd-catalyzed regioselective C-H olefination/cyclization sequence has been developed. This transformation has a wide range of substrates with various functional groups, and the corresponding heterocyclic products were obtained in good yields.

Herein, we report an easily tunable and regioselective Pd-catalyzed allene-alkyne coupling protocol for the stereodivergent synthesis of - and -1,3-enynes using purine allenamine by a simple switch of ligands P(-tolyl)Ph and Boc-Phe-OH. For the first time, we have explored mono--protected amino acids (MPAAs) as ligands in allene-alkyne coupling to furnish -1,3-enynes selectively. This protocol streamlined the access to chiral 1,3-enynes and addressed the long-standing stereoselectivity challenges associated with 1,3-enynes from allene-alkyne coupling.

A unique multimetallic catalyst system that allows for the direct carbonylation of aliphatic and aromatic olefins with carbon dioxide and hydrogen has been developed. The employment of palladium and iridium precursors, in conjunction with 1,2-bis(di--butylphosphinomethyl)benzene (dbpx) or its derivatives as active ligands and Zn(OTf) (OTf: trifluoromethanesulfonate) as an essential acidic additive, has been shown to result in the selective formation of aliphatic esters in CO-based carbonylations, exhibiting unparalleled regioselectivity. Detailed control experiments and mechanistic investigations suggest an initial Ir-catalyzed formation of alkyl formates from carbon dioxide, followed by Pd-catalyzed alkoxycarbonylation at a low CO concentration.

Carbazole scaffolds exhibit diverse applications in materials and biomedical research. We report here a regioselective acylation reaction of carbazole derivatives via a six-membered palladacycle intermediate, featuring the broad functional group compatibility and unique regioselectivity. Additionally, the tolerance of bromo substituents enables further derivatization of the products.

The selective modification of carbohydrates to achieve structural complexity has emerged as a crucial strategy in carbohydrate-based drug development. However, the intricate stereochemistry and densely packed functional groups of carbohydrates pose significant challenges for precise stereoselectivity and regioselectivity control. Herein, we report a palladium-catalyzed, stereospecific, and ligand-controlled regiodivergent glycosyl Suzuki-Miyaura coupling of 3-boryl-glycals, establishing a robust platform for glycoside diversification with versatile C1 and C3 modification.

Alkyl boronic acids and esters are versatile synthetic intermediates that generally require several steps to synthesize. Three-component alkene arylboration reactions allow for the rapid synthesis of alkyl boronic esters. Herein, we report the base-free aerobic Pd-catalyzed three-component alkene arylboration, which allows direct access, in a single step, to alkyl boronic esters from readily available precursors: aryl boronic acids, alkenes, and bis(pinacol)diboron.
