A series of novel 3-substituted-1-[5-methyl-1-(2-pyrimidinyl)-4-pyrazolyl]-1-trans-propenes in order to improve the in vitro and in vivo activity of our prototype 3-[4-(3-chlorophenyl)-1-piperazinyl]-1-[5-methyl-1-(2-pyrimidinyl)-4-pyrazolyl]-1-trans-propene (2) were synthesized and evaluated by assays of growth inhibition against several tumor cell lines in vitro and antitumor activity against some tumor models when dosed both intraperitoneally and orally in vivo. Compounds 7a and 7e, the 3,5-difluorophenyl and 3,5-dichlorophenyl analogues of 2, respectively, showed significantly more potent cytotoxicity than 2 in vitro and potent antitumor activities without causing decrease of body temperature related to side effects.

A concise, one-pot route to oxazoles and furocoumarins has been reported. The key step in this transformation involves in situ generation of N-acyliminium ion (NAI) precursor under catalyst and solvent-free conditions and their further transformations promoted by superacid in the same pot. We have also presented the experimental evidence for the involvement of proto-solvated novel exocyclic N-acyliminium ion. Further, the UV-visible and fluorescence studies revealed that few of the compounds reported here exhibited emission of blue light upon irradiation in EtOH in the region of 404-422 nm.

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.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.name: Oxazolidin-2-one, you can also check out more blogs about497-25-6

Biphasic oxidative cyclocarbonylation of beta-aminoalcohols and 2-aminophenol to synthesize corresponding 2-oxazolidinones were investigated in the presence of ionic liquid stabilized Pd(phen)Cl2 complex. Catalytic comparison results showed that, 1-butyl-3-methyl-imidazolium iodide salts (BMImI) can serve simultaneously as a specific stabilizer to protect the transition metal complex against deactivation, a promoter to increase the catalytic performance and a reaction medium to recycle the catalyst with unprecedented TOF value.

(Chemical Equation Presented) The treatment of N-acyl oxazolidinones of N-benzyl 2-indolecarboxylic acids varying in the substitution pattern of the indole ring with samarium diiodi de at -78C led to the formation of two indole dimer products. The major product isolated in yields from 55 to 59% represents an unsymmetrical dimer arising from 1,4-addition to the 2-indolecarboxylic acid derivative of a possible ketyl-type radical anion intermediate originating from the reduction of the exocyclic carbonyl group of the N-acyl oxazolidinone. The minor dimer, represented by a symmetrical diketone, was produced in yields ranging from 11 to 23%. Even in the presence of an alpha,beta-unsaturated amide, dimerization was the preferred pathway rather than the formation of a gamma-keto amide. Upon treatment with acid, the unsymmetrical indole dimer cyclized to form a diindolequinone. Finally, the N-acyl oxazolidinones of pyrrole-2-carboxylic acid and 3 indolecarboxylic acid preferred in both cases to undergo C-C bond formation with an acrylamide in the presence of SmI2 rather than dimerization.
