A new combination of CuF2/DTBP-catalyzed N-arylation oxazolidinones, amides, amines, and azoles has been explored with arylboronic acid pinacol esters (arylBpin). This methodology also applied to the synthesis oxazolidinone-based marketed drugs, including Rivaroxaban, Linezolid, Sutezolid, Toloxatone. Mechanistic investigations using various spectroscopic techniques DFT studies revealed role DTBP/MeOH in catalytic process.

Mechanistic understanding of asymmetric induction plays a crucial role in designing new catalytic reactions. Reported herein is atroposelective access to C-N axially chiral isoquinolones via rhodium-catalyzed C-H activation N-alkoxy benzamides and annulation with imidoyl sulfoxonium ylides. The coupling system proceeded excellent functional group tolerance, different conditions were identified afford one or the other enantiomeric product each enantioselectivity for representative class ylide reagent, thus making both enantiomers readily available using same catalyst. Experimental computational studies revealed pathway alkylation enantio-determining formal nucleophilic substitution-C-N cyclization that mediated by rhodium catalyst σ-bond metathesis as mechanism. Computational indicated solvent-dependent enatiodivergence originated from levels neutral versus cationic species.

We have found a chameleonic reactivity of imidoyl sulfoxonium ylides. On the one hand, ylides react with electron-deficient reagents, such as alkynyl esters, to lead formation 1,2-dihydro-pyridines. The methyl group attached sulfur atom acts methylene donor. other pyridinium 1,4-zwitterionic thiolates, which leads functionalized pyrroles. Both transformations feature mild reaction conditions and good functional tolerance.
