SYNTHESIS, CRYSTAL STRUCTURE AND BIOACTIVITY OF N-PHENOXYACETYL-2-SUBSTITUTED-1,3-OXAZOLIDINES

A series of novel N-phenoxyacetyl-1,3-oxazolidine derivatives were synthesized by the cyclization and acylation with ethanolamine, ketone and phenoxyacetyl chloride as the starting materials. The structures of all the compounds were characterized by IR, H-1 NMR and C-13 NMR, MS, and elemental analysis. The configuration of 4a was determined by X-ray crystallography. The preliminary biological activity tests indicated that compound 4a could protect soybean against the injury caused by 2,4-D butylate in some extent.

Polyols and Rigid Polyurethane Foams from Cashew Nut Shell Liquid

Cashew nut shell liquid (CNSL) is a natural aromatic oil consisting of a mixture of phenolic structures with a carboxyl group in ortho position and substituted in meta position with a hydrocarbon chain of 15 carbon atoms. The major component of CNSL is anacardic acid (90 %), which is easily decarboxylated to cardanol by distillation. The present work describes the synthesis of new biobased Mannich polyols for rigid polyurethane foams in two steps: synthesis of Mannich bases by reacting phenolic ring of cardanol with N-(2-hydroxyethyl)-1,3-oxazolidine followed by alkoxylation reactions. The polyols were characterized by wet methods (hydroxyl numbers, viscosity, acid value, density, water content, iodine value etc.), spectroscopic methods (FT-IR, H-1 NMR and C-13 NMR) and by Gel Permeation Chromatography. The Mannich polyols from cardanol are excellent replacements for petrochemical derived Mannich polyols based on nonyl phenol. Cardanol-based polyols were used successfully for the preparation of rigid polyurethane foams of good physical-mechanical and fireproofing properties.

Design, synthesis, and anticancer evaluation of some novel thiourea, carbamimidothioic acid, oxazole, oxazolidine, and 2-amino-1-phenylpropyl-2-chloroacetate derived from L-norephedrine

A novel series of thiourea, carbamimidothioic acid, 4, 5-dihydrooxazole-2-thiol, oxazolidine-2thine, and 2-amino-1-phenylpropyl-2-chloroacetate derivatives was designed and synthesized using 2-amino-1-phenylpropan-1-ol (L-norephedrine) as a strategic starting material. The structures of the newly synthesized compounds were established by elemental analyses, IR, and H-1 NMR and C-13 NMR spectral data. The compounds were evaluated for their in vitro anticancer activity against various cancer cell lines. The corresponding acetamide, carbamimidothioic acid, and 2-2-amino-1-phenylpropyl-2-chloroacetate derivatives showed almost the same activity as the standard drug doxorubicin against human breast cancer cell line (MCF-7). Also, the acetamide and 2-thioxoimidazolidin-4-one derivatives exhibited higher activity than the reference drug doxorubicin against human colon cancer cell line (HCT 116).

Three-Component Reactions of Diazoesters, Aldehydes, and Imines Using a Dual Catalytic System Consisting of a Rhodium(II) Complex and a Lewis Acid

A dual catalytic system, dirhodium tetrapivalate/ytterbium(III) triflate, enables the three-component reactions of alpha-alkyl-alpha-diazoesters, aromatic aldehydes, and N-benzylidenebenzylamine derivatives to afford the corresponding beta-amino alcohols in good yields after hydrolysis of the oxazolidine cydoadducts, whereas no beta-amino alcohols are obtained in the absence of ytterbium(III) triflate. A similar dual catalytic system, dirhodium tetraacetate/ytterbium(III) triflate, is found to be effective in accelerating the reactions of alpha-aryl-alpha-diazoesters in high yields. Furthermore, the reactions using dimethyl diazomalonate are described.

Oxazolidine Formation, or Loss of Acid, from Attempted Fluorination of Amide Side-Chain in 2-Nitroimidazoles

Reaction of Etanidazole (a 2-nitroimidazole derivative with an amide side-chain containing a hydroxyethyl group) with triflic anhydride gives, depending on conditions, a trifluoromethyl(sulfonyl)oxazolidine via a cyclization reaction, or a fluorine-free formate derivative; reaction with tosyl chloride gives only a chloroethyl derivative. An attempt to replace a Br-atom in a related propyl-containing amide side-chain by a F-atom forms instead a propylene derivative via loss of HBr. The studies stem from interest in use of 2-nitroimidazoles with fluorine-containing amide side-chains as hypoxia markers.

Synthesis of Enantiopure trans-2,5-Disubstituted Trifluoromethylpyrrolidines and (2S,5R)-5-Trifluoromethylproline

Enantiopure trans-2,5-disubstituted trifluoromethylpyrrolidines were prepared on a several gram scale starting from a readily available chiral fluorinated oxazolidine (Fox). A pure oxazolopyrrolidine intermediate could be obtained after an efficient separation by selective diastereomer destruction. The addition of various Grignard reagents on this oxazolopyrrolidine provided disubstituted pyrrolidines with moderate to complete trans diastereoselectivity. The highly valuable compound (2S,5R)-5-trifluoromethylproline could be synthesized from the same oxazolopyrrolidine intermediate via a Strecker-type reaction.

2,2 ‘-Anhydro-1-(3 ‘,5 ‘-di-O-acetyl-beta-D-arabinofuranosyl)uracil, a cyclouridine nucleoside with a C4 ‘-endo furanosyl conformation

2,2′-Anhydro-1-(3′,5′-di-O-acetyl-beta-D-arabinofuranosyl)uracil, C13H14N2O7, was obtained by refluxing 2′,3′-O-(methoxymethylene)uridine in acetic anhydride. The structure exhibits a nearly perfect C4’-endo (E-4) conformation. The best four-atom plane of the five-membered furanose ring is O-C-C-C, involving the C atoms of the fused five-membered oxazolidine ring, and the torsion angle is only -0.4 (2)degrees. The oxazolidine ring is essentially coplanar with the six-membered uracil ring [r.m.s. deviation = 0.012 (5) angstrom and dihedral angle = -3.2 (3)degrees]. The conformation at the exocyclic C-C bond is gauche-trans which is stabilized by various C-H center dot center dot center dot pi and C-O center dot center dot center dot pi interactions.

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 99395-88-7. Computed Properties of C9H9NO2.

Conjugate addition of thiazolidinethiones and oxazolidinethiones to N-crotonylthiazolidinethiones and -oxazolidinethiones was observed in the presence of excess triethylamine in dichloromethane. The addition takes place by the nitrogen of the heterocycle with high diastereoselectivity. It was observed that the stereoselective addition occurs on the anti-s-cis conformation of the N-enoyl sulfur-containing heterocycle.
