(Salen)chromium(III)/DMAP: An efficient catalyst system for the selective synthesis of 5-substituted oxazolidinones from carbon dioxide and aziridines

(Equation Presented) (Salen)chromium(III)/DMAP was found to be an active catalyst system for the coupling of CO2 and aziridines. The oxazolidinone products were produced in high yield and selectivity from the opening of the aziridine at the most substituted N-C bond. This catalyst system worked well for a wide variety of monosubstituted N-aryl and N-alkyl aziridines as well as a 2,3-disubstituted N-alkyl aziridine.

State-of-the-art catechol porphyrin COF catalyst for chemical fixation of carbon dioxide: Via cyclic carbonates and oxazolidinones

A highly porous, crystalline catechol porphyrin COF was synthesized and applied as an organocatalyst for the chemical fixation of carbon dioxide to synthesize value-added chemicals such as cyclic carbonates and oxazolidinones under solvent-free and transition-metal-free conditions. The high surface area and the functionalities of the COF catalyst act synergistically to activate the starting material. The 2,3-DhaTph shows excellent activity towards cyclic carbonates at the atmospheric pressure of carbon dioxide. Additionally, this catalytic system is recyclable in nature and provides a higher turnover number than previously reported organocatalysts.

Amine functionalized MCM-41 as a green, efficient, and heterogeneous catalyst for the regioselective synthesis of 5-aryl-2-oxazolidinones, from CO2 and aziridines

Covalently linked amine functionalized MCM-41 catalysts were investigated as an efficient, heterogeneous and recyclable catalyst for the coupling of carbon dioxide (CO2) and aziridines providing high conversion with excellent regioselectivity towards 5-aryl-2-oxazolidinones under mild and solvent free conditions. The effect of various reaction parameters, such as temperature, time, and CO2 pressure for the synthesis of 5-aryl-2-oxazolidinones using amine functionalized MCM-41 catalyst was investigated. The optimized protocol was applied to a wide variety of 1-alkyl-2-arylaziridines producing the corresponding 5-aryl-2-oxazolidinones with good yield and excellent regioselectivity. Amine functionalized MCM-41 catalysts were characterized by FT-IR, TG/DTA, high and low angle XRD, and solid state 29Si CPMAS NMR analysis. Furthermore, the catalyst was effectively recycled for five consecutive cycles without any significant loss in its catalytic activity and selectivity under the described reaction conditions. Readily available reagents, mild reaction conditions and effective catalyst recyclability make this protocol simple, convenient, practical and environmentally friendly.
