DESIGN, SYNTHESIS AND BIOLOGICAL ACTIVITY OF NOVEL SULFONYLUREA OXAZOLIDINES

A series of N-[(p-methylphenyl)sulfonyl]-1,3-oxazolidine-3-carboxamide 4 was synthesized by cycloaddition and acylation reaction with alkamine, ketones, and p-methylbenzenesulfonyl isocyanate as the starting materials. The structures of all the compounds were characterized by IR, H-1 NMR, C-13 NMR, MS, and elemental analysis. The configuration of 4d was determined by X-ray crystallography. The preliminary biological test showed that all compounds could protect maize against injury caused by chlorsulfuron to certain extent. The sulfonylurea oxazolidines were possible acted as antagonists of sulfonylureas herbicides at target enzyme pocket site by docking analysis.

Oligomer Formation in Epoxy-Dicyandiamide Systems

For epoxy adhesives based on the hardener dicyandiamide (Dicy), the literature offers different reaction schemes about how epoxy resin and Dicy react. Since these propositions are inconsistent, a complete description of the network formation regarding both tautomeric structures of Dicy does not exist currently. In this study, the oligomer formation before gelation is considered for a pre-cured epoxy system EP [diglycidylether of bisphenol A (DGEBA) + Dicy, mass ratio 100: 7] by reversed-phase HPLC, mass spectrometry, and FTIR spectroscopy analysis. The results verify that DGEBA and Dicy react to 2-cyanimido oxazolidine and ammonia or to 2-imino oxazolidine and cyanamide via Gilbert’s or Zahir’s cyclization, depending on the tautomer. Both chemical pathways go on simultaneously as proven for the first time. Other reactions proposed in the literature (transformation of imino ether to urea or urethane species) are not found under the given conditions (150 degrees C, 60 min).

Chiral Oxazolidine-Fused N-Heterocyclic Carbene Complexes of Rhodium and Iridium and Their Utility in the Asymmetric Transfer Hydrogenation of Ketones

The catalytic potential of new N-heterocyclic carbene ligands, derived from a chiral fused bicyclic ring scaffold with restricted rotation along the C-N bond bearing the chiral auxiliary, has been explored in the transition-metal-mediated asymmetric transfer hydrogenation reactions of ketones. In particular, the chiral oxazolidine-fused N-heterocyclic carbene precursors (3S)-3-R-6-methyl-7-phenyl-2,3-dihydroimidazo[5,1-b] oxazol- 6-ium iodide [R = sec-butyl (1f), i-butyl (2f), isopropyl (3f)] were synthesized from commercially available optically pure amino acids in a multistep sequence that avoids tedious chiral resolution. The reactions of the chiral imidazolium iodide salts 1f-3f with Ag2O yielded the corresponding silver complexes 1g-3g, which were treated with [(COD)MCl](2) (M = Rh, Ir; COD = 1,5-cyclooctadiene) to afford the rhodium(I) and iridium(I) complexes (1h-3h and 1i-3i, respectively). The rhodium(I) and iridium( I) complexes conveniently catalyze the asymmetric transfer hydrogenation of acetophenones for a wide variety of substrates ranging from electron-rich ones such as 4-methylacetophenone, 3,4-dimethylacetophenone, 4-tert-butylacetophenone, and 4-(methylthio) acetophenone to electron-deficient ones such as 4-bromoacetophenone, 4-chloroacetophenone, 4-fluoroacetophenone, 4-nitroacetophenone, and 3-fluoroacetophenone in moderate-to-good yields (ca. 18-95 %) but with low enantioselectivities (ca. 4-41 % ee).

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 16251-45-9, in my other articles.

Norbornanoid Chiral Ketones by Desymmetrization of Dibromoalkenes

New optically active polycyclic ketones 6a-6d, amenable to a large variety of synthetic applications, have been prepared from readily available 2,3-dibromonorbornene and analogs (Scheme 2) via desymmetrization with (-)-ephedrine, followed by hydrolysis under mild acidic conditions. At variance with substrates 4a-4d, the sterically hindered norbornene derivative 4e reacts with the solvent N-methylpyrrolidin-2-one (NMP) leading to the formation of the unusual cyclopropanoid products 8a and 8b.

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. you can also check out more blogs about 6704-31-0. Computed Properties of C3H4O2.

A Zero Cross-Talk Ratiometric Two-Photon Probe for Imaging of Acid pH in Living Cells and Tissues and Early Detection of Tumor in Mouse Model

Acid-base disorders disrupt proper cellular functions, which are associated with diverse diseases. Development of highly sensitive pH probes being capable of detecting and monitoring the minor changes of pH environment in living systems is of considerable interest to diagnose disease as well as investigate biochemical processes in vivo. We report herein two novel high-resolution ratiometric two-photon (TP) fluorescent probes, namely, PSIOH and PSIBOH derived from carbazole-oxazolidine pi-conjugated system for effective sensing and monitoring acid pH in a biological system. Remarkably, PSIOH exhibited the largest emission shift of similar to 169 nm from 435 to 604 nm upon pH changing from basic to acidic with an ideal pK(a) value of 6.6 within a linear pH variation range of 6.2-7.0, which is highly desirable for high-resolution tracking and imaging the minor fluctuation of pH in live cells and tissues. PSIOH also exhibits high pH sensitivity, excellent photostability, and reversibility as well as low cytotoxicity. More importantly, this probe was successfully applied to (i) sense and visualize the pH alteration in HeLa cells caused by various types of exogenous stimulation and (ii) detect and differentiate cancer and tumors in liver tissues and a mouse model, realizing its practical in vitro and in vivo applications.
