An intramolecular cascade cyclization of 2-aryl indoles: efficient methods for the construction of 2,3-functionalized indolines and 3-indolinones

Efficient intramolecular N/O-nucleophilic cyclization of 2-aryl indoles has been developed to afford the corresponding 2-aza-3-oxaindolines and 3-indolinones in 80-95% yield. The methods provided convenient access to fused imidazo[1,2-c]oxazolidinone, oxazolidine, or tetrahydro-1,3-oxazine cores under mild conditions.

Crystal structure and magneto-structural investigation of alkoxido bridged dinuclear Fe(III) complexes with 1,3-oxazolidine ligands

Four 1,3-oxazolidine based ligands (H2L1-H2L4) were synthesized in solvent-free condition from the reaction of amino alcohols (2-amino-2-(hydroxymethyl)-1,3-propanediol or 2-amino-2-ethy1-1,3-propanediol) and 2-acetylpyridine or 2-pyridinecarboxaldehyde at 110 T. Four new dinuclear Fe(III) complexes, [Fe-2(HL1)(N-3)(4)] (1), EFe2(HL2)(N-3)(4)] (2), [Fe-2(HL3)(N-3)(4)] (3) and [Fe-2(HL4)(N-3)(4)] (4), were synthesized with a similar procedure by the reaction of H2L1-4, Fe(NO3)(3).9H(2)O and NaN3 in 1:1:2 molar ratios in methanol. The ligands and complexes were characterized by elemental analysis and spectroscopic methods. The structure of complexes was solved by single-crystal X-ray diffraction analysis which showed complexes 1-4 to be alkoxido-bridged dinuclear Fe(III) complexes. The structural studies indicated that the crystal structure of 2, 3 and 4 consist of a centrosymmetric dinuclear Fe(III) complexes while the asymmetric unit in 1 consists of two halves of the two independent molecules. The Fe(III) ions have similar coordination environments (cis-FeN4O2) in all of 1-4 which can be described as distorted octahedral geometry. The 1,3-oxazolidine ligands act as mononegative tridentate N2O-donor ligand in 1-4. Two azide groups are also coordinated to each Fe(III) ion as terminal monodentate ligands. The alcoholic arms of the 1,3-oxazilidine ligands act as bridging groups between Fe(III) ions and the Fe center dot center dot center dot Fe distances through these bridges are in the range of 3.157-3.198 A. Magnetic studies in 2-300 K range reveal antiferromagnetic interactions between the Fe(III) ions with values for the magnetic coupling constants in the range -9.4 cm(-1) to -9.7 cm(-1), with H =-2(f)(S1S2) (C) 2019 Elsevier Ltd.

Synthesis, Molecular Docking Studies, In Vitro Antimicrobial and Antifungal Activities of Novel Dipeptide Derivatives Based on N-(2-(2-Hydrazinyl-2-oxoethylamino)-2-oxoethyl)-Nicotinamide

A series of linear dipeptide derivatives (4-10) were prepared and evaluated as antimicrobial agents via the synthesis of N-(2-(2-hydrazinyl-2-oxoethylamino)-2-oxoethyl) nicotinamide (4). Compound 4 was reacted with 4-chlorobenzaldehyde or 4-hydroxybenzaldehyde, to give the hydrazones 5 and 6, respectively. On the other hand, Compound 4 was coupled with phenylisocyanate or methylisothiocyanate to give Compounds 7 and 8, respectively. The latter compounds (7 and 8) were coupled with chloroacetic acid to give oxazolidine (9) and thiazolidine (10), respectively. The newly synthesized dipeptide compounds were confirmed by means of their spectral data. The antimicrobial activity of the newly synthesized compounds 4-10 was evaluated by agar well diffusion, and they showed good activity. Compounds 4, 5, and 9 gave the most promising activity in this study. Most of the tested compounds possessed MIC values ranging from 50 to 500 mu g/mL. Furthermore, docking studies were carried out on enoyl reductase from E. coli and cytochrome P450 14 alpha-sterol demethylase (Cyp51) from Candida albicans active sites.

Crystal structure of 5-chloro-1,3-bis[2-(2oxo-1,3-oxazolidin-3-yl)ethyl]-1H-benz-imidazol-2(3H)-one

In the title compound, C17H19ClN4O5, the benzimidazole fused -ring system is essentially planar, the maximum deviation from the mean plane being 0.06 (1) angstrom. Both oxazolidine rings are nearly planar, the maximum deviations from the mean planes are 0.071 (13) and 0.070 (10) angstrom. The dihedral angle between the mean planes of the oxazolidine rings is 69.9 (7). The benzimidazole mean plane makes the dihedral angles of 43.9 (6) and 45.6 (6)degrees with the two oxazolidine rings. In the crystal, the molecules are linked together by weak C-H center dot center dot center dot O hydrogen bonds building zigzag tapes running along the c axis. The Cl atom is split over two positions with an occupancy ratio of 0.567 (7):0.433 (7). This means that the reaction yields two isomers, A and B; the A component has the Cl-atom substituent in the 5-position of the benzimidazolone ring and the B component has the Cl atom in the 6 -position. The two isomers form the disordered co-crystal, with a nearly half Cl atom in each of them, as indicated by the occupancy ratio. The crystal structure was refined as an inversion twin.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 16251-45-9 help many people in the next few years. COA of Formula: C10H11NO2.

Enhancement of chromium uptake in tanning using oxazolidine

Monocyclic and bicyclic oxazolidines were offered at three different junctures of chrome tanning process viz, prior to BCS offer, along with BCS and after basification. It was found that oxazolidine when offered after basification brought about better chromium uptake and reduction of chromium load in the wastewater. Offer of oxazolidine was also varied. Increase in offer of oxazolidine from 0.25% to 1% was found to enhance the chromium uptake and decrease the chromium load in wastewater. But the increase in uptake was not proportionate to the increase in oxazolidine offer more than 0.75%. Offer of 1% Zoldine ZA 78 (monocyclic oxazolidine) and Zoldine ZE (bicyclic oxazolidine) after basification brought about 63.4% and 73.1% enhancement in chrome content in leather compared to control where oxazolidine was not offered. The tone of the wetblue was found to be altered moderately. However this did not call for any process adjustments in wet-finishing. The oxazolidine treated leathers were found to be immensely fuller and tighter. It was found experimentally that offer of 1% of oxazolidine facilitated reduction in the offer of syntans administered for filling and grain tightening by around 46%. Oxazolidine could bring about significant reduction in cost of chemicals apart from resulting environmental benefits due to enhancement of chromium uptake during tanning. (C) 2011 Elsevier B.V.

Ring Enlargement of Three-Membered Heterocycles by Treatment with In Situ Formed Tricyanomethane

Although the chemistry of elusive tricyanomethane (cyanoform) has been studied during a period of more than 150 years, this compound has very rarely been utilized in the synthesis or modification of heterocycles. Three-membered heterocycles, such as epoxides, thiirane, aziridines, or 2H-azirines, are now treated with tricyanomethane, which is generated in situ by heating azidomethylidene-malonodinitrile in tetrahydrofuran at 45 degrees C or by adding sulfuric acid to potassium tricyanomethanide. This leads to ring expansion with formation of 2-(dicyanomethylidene)oxazolidine derivatives or creation of the corresponding thiazolidine, imidazolidine, or imidazoline compounds and opens up a new access to these push-pull-substituted olefinic products. The regio- and stereochemistry of the ring-enlargement processes are discussed, and the proposed reaction mechanisms were confirmed by using N-15-labeled substrates. It turns out that different mechanisms are operating; however, tricyanomethanide is always acting as a nitrogen-centered nucleophile, which is quite unusual if compared to other reactions of this species.

A reaction mechanism is the microscopic path by which reactants are transformed into products. Each step is an elementary reaction. In my other articles, you can also check out more blogs about 6704-31-0. Name: Oxetan-3-one.

Hypervalent Iodine Mediated Oxidative Cyclization of Acrylamide N-Carbamates to 5,5-Disubstituted Oxazolidine-2,4-diones

A metal-free oxidative cyclization of N-Boc-acrylamides with (diacetoxyiodo)benzene in acetic acid produced 5,5-disubstituted oxazolidine-2,4-diones with the formation of a C-O bond in moderate to excellent yields. In addition, the reaction was diastereospecific with N-Boc-2,3-dimethylacrylamides and proceeded with phenyl migration in the case of an N-Boc-2-phenylacrylamide to generate a 5-acetoxy-5-benzyloxazolidine-2,4-dione.
