A facile KF/Al2O3 mediated method for the synthesis of substituted oxazolidinones

2-Substituted oxazolidinones are prepared by a KF/Al2O3 mediated reaction of an oxazolidinone with an alkyl bromide, isocyanate, or sulfonyl chloride.

Valorization of CO2 into N-alkyl Oxazolidin-2-ones Promoted by Metal-Free Porphyrin/TBACl System: Experimental and Computational Studies

The cycloaddition of CO2 to N-alkyl aziridines was efficiently promoted by the convenient TPPH2/TBACl binary catalytic system. The metal-free procedure was effective for the synthesis of differently substituted N-alkyl oxazolidin-2-o

N-heterocyclic olefins as robust organocatalyst for the chemical conversion of carbon dioxide to value-added chemicals

In this report, the activity of N-heterocyclic olefins (NHOs) as a newly emerging class of organocatalyst is investigated for the chemical fixation of carbon dioxide through reactions with aziridines to form oxazolidinones and the N-formylation of amines with polymethylhydrosiloxane (PMHS) or 9-borabicy-clo[3.3.1]nonane (9-BBN) as the reducing agent under mild conditions. The exocyclic carbon atoms of NHOs are highly nucleophilic owing to the electron-donating ability of the two nitrogen atoms. This high nucleophilicity of the NHOs activates CO2 molecules to form zwitterionic NHO–carboxylate (NHO– CO2) adducts, which are active in formylation reactions as well as the carboxylation of aziridines to oxazolidinones.

CO2 Adducts of Phosphorus Ylides: Highly Active Organocatalysts for Carbon Dioxide Transformation

A series of phosphorus ylide (P-ylide) CO2 adducts were synthesized and first used as organocatalysts for CO2 transformation. Detailed studies on the cycloaddition reaction of CO2 with terminal epoxides show that P-ylide CO2 adducts are efficient metal-free and halogen-free organocatalysts to mediate this reaction under ambient conditions (25 °C, 1 atm of CO2). More importantly, the reactions proceeded with a broad scope, high efficiency, and good functional group tolerance and the corresponding cyclic carbonate products were obtained in good to excellent yields (46-99%). Meanwhile, the kinetic study by in situ FTIR methods suggested an intermolecular cooperation effect for effectively accelerating the ring opening of terminal epoxides. Furthermore, from an investigation of the catalytic diversity of P-ylide CO2 adducts, CO2 also could be converted to functionalized cyclic α-alkylidene carbonates, oxazolidinone, and N-methylated and N-formylated amines by organocatalytic reactions.
