CoMFA Study on Novel Substitute Oxazolidine Derivatives

A series of novel Substitute oxazolidine derivatives with potential herbicide safener activity has been modeled using a 3D quantitative structure-activity relationships approach known comparative molecular field analysis (CoMFA). The cross-validated q2 of CoMFA was 0.612, non-cross-validated R2 was 0.986, and F-test value was 120.1, respectively, with the biological activity of the compounds was expressed by pRC30 (root length). The results are critically discussed using a variety of statistical parameters. The CoMFA model was satisfactory and would be useful for the future design of new N-dichloroacetyl oxazolidine herbicide safener.

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 34052-90-9, in my other articles.

Design and synthesis of a folate-receptor targeted diazepine-ring-opened pyrrolobenzodiazepine prodrug conjugate

Pyrrolobenzodiazepines (PBDs) and their dimers (bis-PBDs) have emerged as some of the most potent chemotherapeutic compounds and are currently under development as novel payloads in antibody-drug conjugates (ADCs). However, when used as stand-alone therapeutics or as warheads for small molecule drug conjugates (SMDCs), dose-limiting toxicities are often observed. As an elegant solution to this inherent problem, we designed and synthesized a diazepine-ring-opened bis-PBD prodrug (pro-PBD-PBD) folate conjugate lacking the one of the two imine moieties found in the corresponding free bis-PBD. Upon entering a targeted cell, cleavage of the linker system, including the hydrolysis of an oxazolidine moiety, results in the formation of a reactive intermediate which possesses a newly formed aldehyde as well as an aromatic amine. A fast and spontaneous intramolecular ring-closing reaction subsequently takes place as the aromatic amine adds to the aldehyde with the loss of water to give the imine, and as a result, the diazepine ring, thereby delivering the bis-PBD to the targeted cell. The in vitro and in vivo activity of this conjugate has been evaluated on folate receptor positive KB cells. Sub-nanomolar activity with good specificity and high cure rates with minimal toxicity have been observed.

A novel synthesis of 2-alkyl(aryl)pyrrolidines from proline via 2,3-diphenylhexahydropyrrolo[2,1-b]oxazoles

Diphenyloxapyrrolizidines, products of the reaction between proline and benzaldehyde, are convenient building blocks for synthesizing 2-substituted pyrrolidines. The opening of their oxazolidine ring by treatment with Grignard reagents has been performed and conditions for subsequent removal of the N-hydroxyethyl moiety have been found. Though the yields are moderate (36-42%), the suggested synthesis of 2-alkyl(aryl)pyrrolidines is rather simple since it does not require purification of intermediate products and is easy scalable.

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 84793-24-8. Formula: C16H19NO5.

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.

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).

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).
