2-Oxazolidones are an important class of nitrogen-containing heterocyclic compounds, which have been found to have a wide range of applications as chiral auxiliaries and chemical intermediates in organic synthesis. Moreover, some 2-oxazolidones such as linezolid, toloxatone, and tedizolidare are shown to have high potency as biologically active molecules and are widely used in the pharmaceutical industry. Therefore, many efforts have been dedicated to synthesize these useful cores. Among recent reported synthetic methods, the carboxylative cyclization reactions of inexpensive and easily available allylic and 2,3-allenic amines with CO2 are one of the most interesting and promising synthetic procedures from the viewpoint of developing CO2 as carbon source, since the chemical conversion of CO2 into the value-added chemicals is one of the most important topics in green and sustainable chemistry. In this mini review, we highlight the advances in the synthesis of 2-oxazolidone derivatives through chemical fixation of CO2 to allylic and 2,3-allenic amines from 1987 to 2017, with special emphasis on the mechanistic aspects of the reactions.

Fly ash contains varying amounts of transition metals depending on the fuel, combustion and also downstream emission control process. As certain transition metal ions are known to catalyze solvent degradation, the impact of fly ash is an important consideration for a post-combustion CO2 capture process. Here, five different fly ashes were screened with a representative carbon dioxide loaded aqueous monoethanolamine solution. The addition of fly ash has been found to impact oxidative degradation and product distribution significantly. Eight products have been identified and quantified by LC-TOF method. Some of the new products identified here contain a secondary amine group that could potentially nitrosate further. The rates of formation of these products were determined and found much higher with fly ash compared to MEA alone.

This work reports a novel sustainable two-step method for the synthesis of ethylene glycol (EG) using syngas. In the first step, diethyl oxalate was selectively synthesized via oxidative double carbonylation of ethanol and carbon monoxide (CO) using a ligand-free, recyclable Pd/C catalyst. In the second step, the diethyl oxalate produced underwent subsequent hydrogenation using [2-(di-tert-butylphosphinomethyl)-6-(diethylaminomethyl)pyridine]ruthenium(II) chlorocarbonyl hydride to get EG and ethanol. Thus, the generated ethanol can be recycled back to the first step for double carbonylation. This method gives a sustainable route to manufacture EG using carbon monoxide and hydrogen.

A series of novel HIV integrase inhibitors active against rategravir resistant strains are reported. Initial SAR studies revealed that activities against wild-type virus were successfully maintained at single digit nanomolar level with a wide range of substitutions. However, inclusion of nitrogen-based cyclic substitutions was crucial for achieving potency against mutant viruses. Several compounds with excellent activities against wild-type virus as well as against the viruses with the mutations Q148H/G140S or N155H/E92Q were reported.

Composites were prepared using epoxy resin (ER), carboxyl-terminated butadiene acrylonitrile copolymer (CTBN) and hydroxyl-terminated polybutadiene (HTPB), in different proportions. A chemical link between the HTPB and the epoxy resin was promoted employing tolylene diisocyanate (TDI). The reactions between elastomers and epoxy resin were followed by FTIR. The mechanical properties of the composites were evaluated and the microstructure was investigated through scanning electronic microscopy (SEM). The results showed that the impact resistance of CTBN-modified ER was superior to that of the pure epoxy resin. For the composites with HTPB, the impact resistance increased with elastomer concentration up to three parts per hundred parts of resin (phr). Higher concentrations of HTPB resulted in larger particles and gave lower impact values.

Chemistry graduates have much scope to use their knowledge in a range of research sectors, including roles within chemical engineering, chemical and related industries, healthcare and more. Application In Synthesis of Oxazolidin-2-one,

Carbon dioxide (CO2) is one of the main greenhouse gases that can be utilized as a useful C1 source owing to its abundance, non-toxicity, and renewability. In fact, the transformation of carbon dioxide into valuable organic molecules has attracted considerable attention over the past decades. One-pot multicomponent reactions generally proceed with more than two different raw materials reacting in one pot, thus simplifying the reaction in operation and workup. In this regard, a three-component reaction of CO2, propargylic alcohols, and nucleophiles such as amines, water, and alcohols, to prepare useful carbonyl compounds (e.g., carbamates, oxazolidinones, alpha-hydroxyl ketones, and organic carbonates) is particularly appealing because of the advantages of step and atom economy. From a mechanistic point of view, the three-component reaction of CO2, a propargylic alcohol, and a nucleophile is a type of cascade reaction, involving the carboxylative cyclization of CO2 and propargylic alcohol, and subsequent reaction of a nucleophile with the in situ formed alpha-alkylidene cyclic carbonate. On the other hand, reactions involving CO2 are generally thermodynamically unfavorable because of the thermodynamic stability and kinetic inertness of CO2. Cyclic carbonates are widely used in organic synthesis, and their preparation from vicinal diols and CO2 represents a green synthetic method because biomass is utilized as the source of vicinal diols. However, the low yields of cyclic carbonates are obtained in most cases because of thermodynamic limitations and deactivation of the catalyst by water, which is the co-product of cyclic carbonates. The most commonly used method to improve the yields of cyclic carbonates involves the addition of dehydrating agents. However, decreased selectivity is often observed because of the side reaction of vicinal diols with the hydrolysis products of the dehydrating agent. In addition, the reaction of 2-aminoethanols and CO2 to obtain the corresponding 2-oxazolidinones also encounters the analogous thermodynamic limitation. To solve this problem, an efficient three-component reaction of CO2, propargylic alcohols, and nucleophiles was developed to offer thermodynamically favorable ways for converting CO2 into cyclic carbonates and 2-oxazolidinones with vicinal diols or 2-aminoethanols as nucleophiles. In this strategy, water is not generated and the alpha-alkylidene cyclic carbonate formed from CO2 and propargylic alcohol as the actual carbonyl source reacts with vicinal diol or 2-aminoethanol to give the corresponding cyclic carbonates or 2-oxazolidinones in high yields and selectivity with the simultaneous formation of hydroxyketones. This review aims to summarize and discuss the recent advances in three-component reactions of CO2, propargylic alcohols, and nucleophiles to prepare various carbonyl compounds promoted by both metal catalysts and organocatalysts.
