Synthetic Route of 16112-21-3, An article , which mentions 16112-21-3, molecular formula is C14H11NS. The compound – 2-(4-Methylphenyl)benzothiazole played an important role in people’s production and life.

Herein, nickel-based metal-organic framework, Ni-MOF-74, was synthesized by a solvothermal method and its properties was characterized by a host of techniques. Ni-MOF-74 exhibited exceptional catalytic activity toward the direct arylation of azoles via C[sbnd]H activation while other Ni-MOFs, nickel-based heterogeneous systems, and homogeneous counter parts displayed lower activity. Optimal conditions involved the use of Li2CO3 or KCl salts in diglyme solvent in 18 h and no additional ligand is required. This is the first and unprecedented report using KCl salt as promoter for arylation of heterocycles. By avoiding the use of strong bases and oxidants, optimized conditions are compatible with wide range of functional groups and heterocycles. Furthermore, by taking advantage of large aperture size of Ni-MOF-74, we are able to utilize optimized conditions to successfully synthesize several bioactive arylated azole derivatives. Previous studies using heterogeneous catalysts to approach these bioactive compounds are not performed in the literature. Leaching tests indicated that homogeneous catalysis via leached active nickel species is unlikely. Thus, the catalyst was facilely separated from the reaction mixture and reused several times without significant degradation of the catalytic reactivity.

A mild and efficient substrate-assisted C-H bond cyanation of 2-arylbenzothiazoles has been developed using CuCN as cyano-group source. The reaction exhibits broad functional groups tolerance giving the desired products in moderate to excellent yields. Regioselective cyanation was in favor of the less sterically hindered position to those meta-substituted substrate.

The heterogeneous catalyst exhibited excellent activity and reusability (up to 8 times) in the synthesis of highly functionalized piperidines. Also, synthesis of 2-arylbenzimidazoles and 2-arylbenzothiazoles have been efficiently developed under mild condition from o-phenylenediamines or 2-aminothiophenol with aryl aldehydes via one-step process using catalytic amount (2.0?mol%) of nanocatalyst in air atmosphere as a green oxidant. The heterogeneous catalyst was characterized by scanning electron microscopy, atomic force microscopy, inductively coupled plasma spectrometry, thermogravimetry for analysis of nitrogen adsorption, and FT-IR spectroscopy.

A glucopyranose functionalized star-shaped oligomer, N-tris{4,4′,4″- [(1E)-2-(2-{(E)-2-[4-(benzo[d]thiazol-2-yl)phenyl]vinyl}-9,9-bis(6-2-amido-2- deoxy-1-thio-beta-D-glucopyranose-hexyl)-9H-fluoren-7-yl)vinyl]phenyl} phenylamine (TVFVBN-S-NH2), is synthesized for two-photon fluorescence imaging. In water, TVFVBN-S-NH2 self-assembles into nanoparticles with an average diameter of ?49 nm and shows a fluorescence quantum yield of 0.21. Two-photon fluorescence measurements reveal that TVFVBN-S-NH2 has a two-photon absorption cross-section of ?1100 GM at 780 nm in water. The active amine group on the glucopyranose moiety allows further functionalization of TVFVBN-S-NH2 with folic acid to yield TVFVBN-S-NH2FA with similar optical and physical properties as those for TVFVBN-S-NH2. Cellular imaging studies reveal that TVFVBN-S-NH2FA has increased uptake by MCF-7 cells relative to that for TVFVBN-S-NH2, due to specific interactions between folic acid and folate receptors on the MCF-7 cell membrane. This study demonstrates the effectiveness of glycosylation as a molecular engineering strategy to yield water-soluble materials with a large two-photon absorption (TPA) cross-section for targeted cancer-cell imaging. Biological imaging: A star-shaped two-photon absorbing material (see scheme) with folic acid functionalization has been synthesized for targeted two-photon fluorescence imaging of MCF-7 cancer cells.
