Synthetic Route of 497-25-6, Because a catalyst decreases the height of the energy barrier, its presence increases the reaction rates of both the forward and the reverse reactions by the same amount.497-25-6, Name is Oxazolidin-2-one, molecular formula is C3H5NO2. In a article，once mentioned of 497-25-6

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.

category: oxazolidine, In chemical reaction engineering, simulations are useful for investigating and optimizing a particular reaction process or system. 102029-44-7, Name is (R)-4-Benzyl-2-oxazolidinone, molecular formula is C10H11NO2. In a Article，once mentioned of 102029-44-7

Incubation of [2-2H]-(2S,3R)-2-methyl-3-hydroxypentanoyl-SACP ([2-2H]-1a) with the epimerizing ketoreductase domain EryKR1 in the presence of a catalytic amount NADP+ (0.05 equiv) resulted in time- and cofactor-dependent washout of deuterium from 1a, as a result of equilibrium isotope exchange of transiently generated [2-2H]-2-methyl-3- ketopentanoyl-ACP. Incubations of [2-2H]-(2S,3S)-2-methyl-3-hydroxy- pentanoyl-SACP with RifKR7 and with NysKR1 also resulted in time-dependent loss of deuterium. By contrast, incubations of [2-2H]-(2R,3S)-2-methyl-3- hydroxypentanoyl-SACP and [2-2H]-(2R,3R)-2-methyl-3-hydroxypentanoyl- SACP with the non-epimerizing ketoreductase domains EryKR6 and TylKR1, respectively, did not result in any significant washout of deuterium. The isotope exchange assay directly establishes that specific polyketide synthase ketoreductase domains also have an intrinsic epimerase activity, thus enabling mechanistic analysis of a key determinant of polyketide stereocomplexity.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. category: oxazolidine, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 102029-44-7, in my other articles.

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.

A simple procedure for the asymmetric synthesis of lignans via chiral beta-benzyl-gamma-butyrolactones has been developed. The key benzylbutyrolactone intermediates were efficiently synthesized using a six-step procedure, starting from 3,4-(methylenedioxy)cinnamic acid. The key step in this sequence was a highly diastereoselective alkylation of an N-acyloxazolidinone enolate. The resulting beta-benzyl-gamma-butyrolactones were subsequently transformed into the benzylidene lignans gossypifan and savinin (hibalactone) via aldol condensation-dehydration reactions, and into the dibenzylbutyrolactone lignan 4?-demethylyalein, through alkylation. Oxidation of 4?-demethylyatein with 2,3-dichloro-5,6-dicyano-1,4-benzoquinone (DDQ) afforded cis- and trans-benzylidenebenzylbutyrolactones, whereas oxidation with DDQ/TFA gave 4?-demethyl-deoxyisopodophyllotoxin.
