A tunable route to both isomers of benzo[d]imidazothiazole has been developed through copper-promoted cycloaddition of alpha-methylenyl isocyanides with benzothiazoles. When the C2 position of benzothiazole is linked to a C-H or C-C bond, benzo[d]imidazo[2,1-b]thiazoles are obtained through a novel rearrangement via C-S bond cleavage and formation of a new C-S bond. When 2-chloro- or 2-bromobenzothiazoles are used under the same reaction conditions, the isomeric benzo[d]imidazo[5,1-b]thiazoles are formed selectively. These reactions proceed smoothly in moderate to excellent yields at room temperature, and a wide range of functional groups are tolerated.

The triazole analogs were obtained via. multistep synthesis sequence beginning with ethyl nicotinoate 3 which on treatment with hydrazine hydrate yields nicotinoyl hydrazide 4. Intermolecular cyclisation of 4 with 4-methylbenzoic acid in presence of phosphorous oxy chloride affords 2-(3-pyridyl)-5-(4-methylphenyl)-1,3,4-oxadiazole 5. Condensation of 5 with various substituted 2-hydrazino benzothiazole 2a-j results in 3-(3-pyridyl)-5-(4-methylphenyl)-4-(N-substituted-1,3-benzothiazol-2-amino) -4H-1,2,4-triazole 6a-j analogs. All the compounds have been characterized by elemental analysis, IR, 1H NMR, 13C NMR and mass spectral data. In vitro antitubercular activity was carried out against Mycobacterium tuberculosis H37Rv strain using Lowenstein-Jensen medium and antimicrobial activity against various bacteria and fungi using broth microdilution method. Compounds 2e, 6a, 6b, 6c, 6d, 6g, 6h and 6i emerged as promising antimicrobials. It was also observed that the promising antimicrobials have proved to be better antituberculars. Compound 6j showed better antitubercular activity compared to rifampicin. 3-(3-Pyridyl)-5-(4-methylphenyl) -4-(N-substituted-1,3-benzothiazol-2-amino)-4H-1,2,4-triazole 6a-j were synthesized and their antitubercular activity against H37Rv and antimicrobial activities have been tested.

Application of 32137-76-1, An article , which mentions 32137-76-1, molecular formula is C10H9NO2S. The compound – Ethyl 1,3-benzothiazole-2-carboxylate played an important role in people’s production and life.

Abstract: A new series of benzothiazole amide derivatives (9a?l) were synthesized and characterized by Fourier-transform infrared (FT-IR), mass, and 1H and 13C nuclear magnetic resonance (NMR) spectroscopic techniques. The antimitotic activity of the newly synthesized compounds was determined by the Allium assay method, from which mitotic index values were calculated. Here, 9g (14.0 %) and 9l (14.5 %) showed mitotic index values most comparable to that of standard drug (14.4 %), while the remaining compounds showed lower mitotic index values; hence, these compounds inhibit the regular cell division process and are the most promising antimitotic agents. Based on the structural activity relationship, the maximum percentage inhibition was observed for compounds containing electron-withdrawing group, revealing enhanced antimitotic activity, while compounds with electron-donating groups such as furan (9g) and methyl (9l) were comparable to standard. The newly synthesized compounds were also screened for antimicrobial activity, with some of them showing remarkable activity. Graphical Abstract: [Figure not available: see fulltext.]

A systematic study of the cross-coupling capability of the 4- and 5-positions of 2-phenylthiazoles and -oxazoles under Stille conditions is presented. The azoles were both applied as stannanes and as the halide component. The obtained results were compared regarding the position of the halide and Bu3Sn group. In order to establish a general reactivity platform for those heterocyclic systems, a broad variety of aromatic and heteroaromatic halides were coupled and some significant differences concerning the coupling properties of the investigated systems were observed.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 141305-40-0 is helpful to your research., Synthetic Route of 141305-40-0

In an article, published in an article, once mentioned the application of 137-00-8, Name is 4-Methyl-5-thiazoleethanol,molecular formula is C6H9NOS, is a conventional compound. this article was the specific content is as follows.Application In Synthesis of 4-Methyl-5-thiazoleethanol

TBDMS (t-BuMe2Si, tert-butyldimethylsilyl) ethers of a variety of phenols have been deprotected with KHF2 in MeOH, at room temperature. Carboxylic ester and labile phenolic acetate were unaffected under these conditions. In competition reactions between TBDMS ethers of a phenol and two primary benzylic alcohols, the phenolic ether underwent cleavage whereas the alcohol ethers remained intact. From a substrate containing both a phenolic hydroxyl group and a secondary, doubly benzylic hydroxyl group protected as TBDMS ethers, the phenol was rapidly and selectively released. Cleavage of TBDMS, TBDPS, and TIPS ethers of a phenol was also compared. TBDMS and TBDPS ethers underwent cleavage at room temperature within 30 minutes, whereas removal of the TIPS ether required 2.5 hours. Ease of cleavage appears to be TBDMS ? TBDPS > TIPS. At 60C, TBDMS ethers of primary benzylic, allylic, and unactivated alcohols can be efficiently desilylated over a prolonged period (13-17 h). Thus, KHF2 proves to be a mild and effective reagent for the selective desilylation of phenol TBDMS ethers at room temperature.

Convenient general procedures have been developed for preparing series of thiazole-4- and -5-carboxylates containing alkyl and halogeno substituents.While both series of esters show i.r. carbonyl doublets caused by rotational isomerism, the more intense absorptions of the 4-carboxylates are the lower wavenumber components, whereas those of the 5-carboxylates are the higher wavenumber components.In both series the stronger bands arise from the thermochemically more stable forms; identification of these forms as the carbonyl O,S-syn-s-trans rotamers is more certain with the 4-carboxylates than with the 5-carboxylates.
