Metal-catalyzed radical-type transformation of unactivated alkyl halides with C-C bond formation under photoinduced conditions

Recent advances in the metal-catalyzed radical-type transformation of unactivated alkyl halides with C-C bond formation under photoinduced conditions are summarized. In general, an alkyl radical is generated as the key intermediate under visible light irradiation from unactivated alkyl halides. Different metal catalysts including Pd, Cu, Mn, Au, and Ir are reported to promote the conversion effectively. Additionally, a strategy by merging photoredox and transition metal catalysis is successfully applied in the cross-electrophile coupling of alkyl halides. During the reaction process, the undesired beta-hydride elimination is suppressed. Usually, a broad reaction scope is observed, including tertiary, secondary, and primary alkyl halides, with good functional group compatibility.

Synthesis and ESI-MS/MS fragmentation study of two new isomeric oxazolidin-2-one derivatives

Two new isomeric oxazolidin-2-one derivatives have been synthesized through reaction of (E)-3-styrylquinoxalin-2-one with bis-dichloroethylamine hydrochloride in presence of potassium carbonate. The structures of the formed products were established by NMR and mass spectroscopy. The fragmentation patterns of the two novel synthesized oxazolidin-2-ones (1, 2), possessing the same backbone structure, were investigated using electrospray ionization mass spectrometry (ESI-MS) and tandem mass spectrometry (MS/MS) techniques. A simple methodology, based on the use of ESI (positive ion mode) and by increasing the declustering potential in the atmospheric pressure/vacuum interface, collision induced dissociation (CID), was used to enhance the formation of the fragment ions. In general, the novel synthetic oxazolidin-2-one derivatives afforded, in the gas phase, protonated molecules leading to the confirmation of the molecular masses and chemical structures of the studied compounds. The breakdown routes of the protonated molecules were rationalized by conducting low-energy collision CID-MS/MS analyses (product ion scans) using. The structural similarity between the two studied oxazolidin-2-ones explains the similarity observed in their CID-MS/MS spectra and their fragmentation pathways. ESI-MS/MS recorded with increased collision energy values permits us to observe different product ions and allow us to differentiate the two studied isomers. ESI-MS and CID-MS/MS analyses have thus proven to be a specific and very sensitive method for the structural investigation of the two novel synthesized oxazolidin-2-one derivatives.

Samarium diiodide as an efficient catalyst for the conversion of N-acyloxazolidinones into esters

The transformation of N-acyloxazolidinones into esters is readily performed using catalytic amounts of samarium diiodide in tetrahydrofuran at room temperature. This method allows the isolation of various esters without racemization in the case of scalemic substrates and the recovery of oxazolidinones in good yields. Georg Thieme Verlag Stuttgart.

Chemical fixation of CO2 to allylic (alpha-Allenylic) amines: A green route to synthesis of functionalized 2-Oxazolidones

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.

Isocyanurate transformation induced healing of isocyanurate?oxazolidone polymers

Isocyanurate?oxazolidone (ISOX) polymers have been reported as a novel, intrinsically self-healable thermoset, and their healing mechanism under the effect of nucleophiles, such as tertiary amines and pyridines during polymerization, is thoroughly investigated in this study. This work provides evidence that the healing behavior of the polymers results part from the transformation of isocyanurate to oxazolidone on the fracture surfaces of the ISOX polymers at elevated temperatures. The isocyanurate transformation is characterized by chemical composition of the ISOX polymers before and after a predetermined healing procedure, through a combination characterization of Fourier transform infrared spectroscopy and carbon nuclear magnetic resonance spectroscopy. From the chemical composition of the ISOX polymers, an increased oxazolidone fraction is observed after the healing event, which verifies the hypothesized healing mechanism. By correlating the change in oxazolidone fraction in the polymers during the healing event, with the corresponding healing performance of the polymers, healing efficiencies of the polymers are shown to be inversely proportional to the ratio of oxazolidone to isocyanurate in the polymers. The transformation to oxazolidone is also shown to be dependent on two variables, nucleophilicity of the polymerization catalyst and duration of the postcure. The isocyanate and epoxide polymerization mechanism in the presence of nucleophiles is also investigated to explain the effect of the catalyst nucleophilicity on the chemical composition as well as the healing performance of the ISOX polymers.

Substituted cis-hydrindan-4-ones by sequential cycloadditions

The synthesis of substituted cis-hydrindan-4-ones is reported. Particular emphasis was placed on the diastereoselective construction of quaternary stereogenic ring carbon atoms. An intermolecular asymmetric Al(III)-promoted (4+2)-cycloaddition served as the principal C/C-connecting tool. Opportunities for the further structural elaboration of the (4+2)-cycloadducts were explored.

Thermal degradation comparison of amino acid salts, alkanolamines and diamines in CO2 capture

In the selection of candidates for post-combustion CO2 absorption, solvent degradation has become a general concern due to the significant impact on operational cost and the intention to use thermal compression from high temperature stripping to minimize the overall process energy. In this research, structural analogs of amino acid salts, alkanolamines and diamines were thermally degraded in order to explore their thermal stability from a structural standpoint. Functional groups, amine orders and steric effect were investigated for their impact on amine thermal degradation. Primary amines with chain structures showed a thermal stability trend as diamine > alkanolamine > amino acid salt. For alknolamine and diamine structural isomers, the primary amines are more stable than the secondary amines. Steric hindrance around the amine group was shown to play a positive role in protecting amines against thermal degradation.

Efficient and recyclable Cu2(BDC)2(BPY)-catalyzed oxidative amidation of terminal alkynes: Role of bipyridine ligand

We have described an efficient method for oxidative cross coupling reactions between activated N-H amines and terminal alkynes using heterogeneous Cu2(BDC)2(BPY) as recyclable catalyst (BDC = benzene-1,4-dicarboxylate; BPY = 4,4?-bipyridine). The optimal conditions involved the use of inexpensive NaHCO3 base and oxygen as terminal oxidant in toluene solvent at 80C. Reactions proceeds efficiently, and high selectivity with only trace amount of diynes as well as good yields were achieved in a short reaction time. The Cu2(BDC)2(BPY) exhibited excellent catalytic activity and selectivity as compared to other Cu-MOFs on a broad reaction scope. Interestingly, the presence of bipyridine ligand was shown to enhance the catalyst stability. Thus, the Cu2(BDC)2(BPY) could be facilely separated from the reaction mixture by simple centrifugation and could be reused several times with only a slight decrease in catalytic activity.
