Abstract: Herein, we describe the synthesis of twenty-one novel water-soluble monocationic 2-aryl/heteroaryl-substituted 6-(2-imidazolinyl)benzothiazole mesylates 3a?3u and present the results of their anti-proliferative assays. Efficient syntheses were achieved by three complementary simple two-step synthetic protocols based on the condensation reaction of aryl/heteroaryl carbaldehydes or carboxylic acid. We developed an eco-friendly synthetic protocol using glycerol as green solvent, particularly appropriate for the condensation of thermally and acid-sensitive heterocycles such as furan, benzofuran, pyrrole, and indole. Screening of anti-proliferative activity was performed on four human tumour cell lines in vitro including pancreatic cancer (CFPAC-1), metastatic colon cancer (SW620), hepatocellular carcinoma (HepG2), and cervical cancer (HeLa), as well as in normal human fibroblast cell lines. All tested compounds showed strong to moderate anti-proliferative activity on tested cell lines depending on the structure containing aryl/heteroaryl moiety coupled to 6-(2-imidazolinyl)benzothiazole moiety. The most potent cytostatic effects on all tested cell lines with IC 50 values ranging from 0.1 to 3.70 mu M were observed for benzothiazoles substituted with naphthalene-2-yl 3c, benzofuran-2-yl 3e, indole-3-yl 3j, indole-2-yl 3k, quinoline-2-yl 3s, and quinoline-3-yl 3t and derivatives substituted with phenyl 3a, naphthalene-1-yl 3b, benzothiazole-2-yl 3g, benzothiazole-6-yl 3h, N-methylindole-3-yl 3l, benzimidazole-2-yl 3n, benzimidazole-5(6)-yl 3o, and quinolone-4-yl 3u with IC 50 values ranging from 1.1 to 29.1 mu M. Based on obtained anti-proliferative activities, 3D-QSAR models for five cell lines were derived. Molecular volume, molecular surface, the sum of hydrophobic surface areas, molecular mass, and possibility of making dispersion forces were identified by QSAR analyses as molecular properties that are positively correlated with anti-proliferative activity, while compound?s capability to accept H-bond was identified as a negatively correlated property. Comparison of molecular properties identified for different cell lines enabled assumptions about similarity of mode of action through which anti-proliferative activities against different cell lines are accomplished. Novel compounds that are predicted to have enhanced activities in comparison with herein presented ones were designed using 3D-QSAR analysis as guideline.

Synthetic Route of 4741-62-2, Because a catalyst decreases the height of the energy barrier, its presence increases the reaction rates of both the forward and the reverse reactions by the same amount.4741-62-2, Name is 5-Methoxyisobenzofuran-1(3H)-one, molecular formula is C9H8O3.

Addition of lateral lithiated amides and phthalide anions to enantiopure sulfinimines (N-sulfinyl imines) represents a new approach for the asymmetric synthesis of 3-substituted isoquinolones and 3-substituted 4-hydroxy isoquinolones, respectively, important chiral building blocks for isoquinoline alkaloid synthesis. In one example 3-phenylisoquinolone (-)-15b was prepared in >95% ee by treatment of amide ion 10b with sulfinimine (S)- (+)-11 and subsequent deprotection of the N-sulfinyl auxiliary and cyclization. Oxaziridine-mediated hydroxylation of the anion of 16 afforded 4-hydroxy isoquinolone 19, which was transformed into 4-hydroxy-3- phenyltetrahydroisoquinoline (-)-22. In another approach 22 was prepared more directly by addition of phthalide ion 26 to (S)-(+)-11, creating the two stereogenic centers simultaneously. The selectivity proved to be highly counterion dependent.

The answer is in thermodynamics and kinetics.In a document type is Article, and a compound is mentioned, 569-31-3, 6,7-Dimethoxy-3H-1-isobenzofuranone, introducing its new discovery.

The annulation of phthalides with alpha-alkyl/arylacrylates in the presence of LDA/LHMDS is shown to directly give alkyl/aryl-1-naphthols. The method involving a novel dealkoxycarbonylation obviates the regiochemical issues in the synthesis of polysubstituted naphthalenes, and it forms the key step in a three-step total synthesis of arnottin I, a naphthobenzopyranone natural product.

(Chemical Equation Presented) The first general methodology for the gram-scale preparation of previously overlooked beta-(hetero)aryl-alpha- nitro-alpha,beta-enals (3) is reported. Condensation of (hetero)aromatic aldehydes with 2-nitroethanol gave the E-isomers of uncommon beta-(hetero)aryl-alpha-hydroxymethyl-alpha,beta-unsatured-nitroalkenes (2), as determined by NOE and X-ray studies. alpha-Nitro-alpha,beta-enals 3 were subsequently obtained by hypervalent iodine oxidation of 2 as E-Z-mixtures in solid form. They showed varied stability and solvent-dependent thermal-promoted and photopromoted E-Z interconversion. Starting with furfural, experimental conditions were developed to prepare the corresponding nitroenal 3a enriched in either the E or the Z isomer: E-3a/Z-3a ? 90/10 and 20/80, respectively. In contrast with other structurally related compounds, nitroenals 3 have their (hetero)aryl-vinyl unit and their formyl and nitro groups all in a planar arrangement, both in solid form and in solution; accordingly, they are colored compounds with predicted high dipole moments. As deduced from solution-NMR and X-ray data, the C=C and the C=O double bonds in 3 are exclusively s-cis-oriented; this disposition corresponds in fact to the DFT-computed most stable conformer.

The answer is in thermodynamics and kinetics.In a document type is Article, and a compound is mentioned, 4687-25-6, Benzofuran-3-carbaldehyde, introducing its new discovery.

A convenient approach towards enantiopure (R) and (S) isomers of 2,2,2-trifluoro-1-(heteroaryl)ethanols was developed. The enzyme-catalyzed kinetic resolution of the corresponding racemic mixtures was achieved by using a two-step protocol that involved an acylation and a hydrolysis step in the presence of Burkholderia cepacia and CAL-B lipase (Candida antarctica lipase B), respectively. Fourteen compounds were resolved on a multigram scale by using this approach. The observed enantioselectivities correlated well with the results of molecular docking experiments.

Application of 24673-56-1, Chemistry is the experimental science by definition. We want to make observations to prove hypothesis. For this purpose, we perform experiments in the lab. 24673-56-1, Name is 3-Methylbenzofuran-2-carboxylic acid,introducing its new discovery.

We report the Pd(II)-catalyzed, bidentate directing group (BDG)-assisted arylation and successive arylation/intramolecular amidation of gamma-C(sp3)-H bonds. The Pd(II)-catalyzed BDG-assisted C-H activation and functionalization of the beta-C(sp3)-H bonds of carboxylic acids are well documented, but only a few reports are available that deal with the BDG-directed functionalization of the gamma-C(sp3)-H bonds. Various 3-methylthiophene/furan-2-carboxamides (1a-e) were derived from their corresponding carboxylic acids and bidentate directing groups. These compounds were then used as substrates to investigate the arylation and successive arylation/intramolecular amidation of the gamma-C(sp3)-H bonds. The gamma-C(sp3)-H arylation arose from the Pd(II)-catalyzed reactions of these compounds with aryl iodides with reaction periods of 4-24 h (except a few reactions which required 36 or 48 h). Notably, these reactions led to the construction of various unsymmetrical diarylmethane scaffolds, such as thiophene/furan-based arylheteroarylmethanes (3-6). Prolonging the reaction period to 48-70 h led to successive gamma-C(sp3)-H arylation/intramolecular amidation and the construction of both C-C and C-N bonds. Accordingly, these reactions led to the construction of new classes of pyrrolidone-ring annulated thiophene/furan-based heterocyclic scaffolds (e.g., 4,5-dihydro-6H-thieno[2,3-c]pyrrol-6-ones (8), 4,5-dihydro-6H-furo[2,3-c]pyrrol-6-ones (10), and 1-phenyl-1,2-dihydro-3H-benzo[4,5]thieno[2,3-c]pyrrol-3-ones (12)), and notably, compounds 8, 10, and 12 resemble the skeletons of 3-phenylisoindolin-1-ones.
