Biobased urea nowadays attracts increasing attention as a biomass resource with giant potential, which benefits from the development of biobased ammonia and ecological sanitation system. Urea is an ideal feedstock for chemical industry and developing new urea-based polymer materials can take advantage of the urea resource. In this work, a class of renewable linear polyesters, namely polyisocyanuratoesters (PICEs) were synthesized from a urea-based monomer bis(2-carbomethoxyethyl) isocyanurate and biobased aliphatic diols. Compared with conventional aliphatic polyesters, PICEs containing isocyanurate rings in the polymer chain backbone exhibit outstanding flame retardancy that both PICE-4 (the number ?4? refers to the number of methylene in diols, e.g. 4 for butylene and 6 for hexylene) and PICE-6 have high limiting oxygen index values over 30%. In the UL 94 tests, PICE-6 reaches V-1 rating; while V-2 is found for PICE-10. All PICEs exhibit similar pyrolysis behavior that the temperatures of 5% weight loss are around 320C. PICEs are found to have glass transition among 20C-45C. No crystallization behavior is observed without annealing except for PICE-10, which can crystallize even at room temperature.

An efficient Prins reaction of silyl glyoxylates in the presence of an aqueous ZnCl2 complex as a catalyst was developed, providing functionalized tertiary alpha-silyl alcohols in high yields under mild conditions. A preliminary investigation indicated that the aqueous ZnCl2 complex acted as a dual functional catalyst of Br°nsted and Lewis acid to activate the carbonyl groups of silyl glyoxylates via a dual-activation model.

We theoretically estimated pKa of N-containing heterocycles in DMSO by a quantum chemistry method with a polarizable continuum model, which was previously developed for estimating pKa of molecules in water. We numerically show the present scheme also works for DMSO solvent as accurately as for water. According to the obtained result, we confirmed transferability of obtained parameters in calculating pKa using Gibbs energy in different solvent conditions.

Application of 497-25-6, In chemical reaction engineering, simulations are useful for investigating and optimizing a particular reaction process or system. 497-25-6, Name is Oxazolidin-2-one, molecular formula is C3H5NO2. In a Review，once mentioned of 497-25-6

A major remark made by observers relates to the focus of the pharmaceutical industry on ‘me-too’ drugs rather than ‘first-in-class’ drugs, the latter are considered to be ‘truly’ innovative medicines. Although the subject is heavily debated, chemists in project teams around the globe are routinely following up compounds from competitors. An important strategic consideration is the degree of chemical modification of the original structure required for success. Here, we present an analysis of the DiMasi and Faden set of first-in-class and follow-on drug pairs (n = 74); showing that 70% of them are structurally very similar, meaning that they are characterized by minimal structural variations. This highlights the fact that even simple atomic variations can cause drastic changes in molecular properties responsible for therapeutic advantages.

Synchrotron radiation and synchrotron based spectroscopic techniques have found important applications in the study of isolated molecular species of biological interest. In this paper, some examples of spectroscopic and dynamic studies of amino acids and small peptides, nucleobases and pharmaceuticals are reviewed. Opportunities offered by the advent of new radiation sources combined with novel methods for the production of beams of these molecules are also discussed.

This review is focused on the synthesis of isoxazolidines as the core of biologically active compounds having anti-cancer, antiviral, antibacterial and anti-inflammatory properties. The isoxazolidine ring, as mimetic of ribose, has been principally synthesized with high regio-, stereo- and enantioselectivity, applying the methodology of 1,3-dipolar cycloaddition, involving nitrones and alkenes as dipoles and dipolarophiles, respectively. The easy accessibility of this ring by this approach, then, makes this heterocycle, particularly suitable for the synthesis of small molecules useful in the design of new and modified drugs.

The potential utility of systematic synthetic strategy will be applicable to efficient generations of chemical libraries of compounds to find ‘hit’ molecules.Read on for other articles about 1192-07-0Related Products of 1192-07-0

This work presents the characterization of 5-[(3,5-dimethylphenoxy)methyl]-1,3-oxazolidin-2-one (metaxalone) by DFT calculations and spectral techniques. The spectral analysis was carried out by using FT-IR and FT-Raman and 13C and 1H nuclear magnetic resonance (NMR) techniques. The FT-IR and FT-Raman spectrum were recorded in the range of 4000 to 400cm-1 and 4000 to 50cm-1 respectively. The over estimations of the calculated harmonic wavenumbers were efficiently corrected by the aid of a specific scaling procedure. 13C and 1H NMR chemical shifts of the molecule were calculated using gauge independent atomic orbital method (GIAO) and were compared with the experimental results. The molecular structure, fundamental vibrational frequencies and electronic structure calculations are carried out by density functional theory (DFT) method and B3LYP/ 6-311++G(d,p) basis set. Frontier molecular orbital energies, global reactivity descriptors and molecular electrostatic potential (MEP) were estimated. The thermodynamic properties at different temperatures were calculated revealing the correlations between standard heat capacities, entropy and enthalpy changes with temperatures.

Efficient CuI/1,10-phen-catalyzed three-component cascade reaction of propargylic alcohols, CO2, and 2-aminoethanols has been firstly developed for the thermodynamically favourable preparation of 2-oxazolidinones. In the presence of commercially available CuI, 1,10-phen (1,10-phenanthroline) and t-BuOK, the cascade reaction afforded the desired products in good to excellent yields with a broad substrate scope (14 examples). The predicted copper complex Cu2I2(phen)2 in situ formed from CuI and 1,10-phen could activate the triple bond through coordination. The isolation of alpha-alkylidene cyclic carbonate as the reaction intermediate suggests that the carboxylative cyclization of propargylic alcohol with CO2, followed by ring-opening reaction, is involved in the one-pot three-component cascade reaction.
