A highly efficient and facile method has been described for the synthesis of substituted 2-aminothiazoles in water without any added catalyst or co-organic solvent. The reaction was carried out at ambient temperature and the products were obtained in excellent isolated yields. The developed protocol is successfully applied for the preparation of an anti-inflammatory drug, fanetizole.
A simple and practical procedure for the synthesis of 2‐aminothiazoles from α‐tosyloxyketones and thioureas is described using PEG‐400[poly(ethylene glycol‐400)] at ambientconditions. The developed protocol is successfully applied for the preparation of an anti‐inflammatory drug, Fanetizole.
A library of thiazoles and selenothiazoles were synthesized via Ir-catalyzed ylide insertion chemistry. This process is a functional group, particularly heterocycle-substituent tolerant. This was applied to the synthesis of fanetizole, an anti-inflammatory drug, and a thiazole-containing drug fragment that binds to the peptidyl-tRNA hydrolase (Pth) in Neisseria gonorrheae bacteria.
通过 Ir 催化叶立德插入化学合成了噻唑和硒代噻唑库。这个过程是一个官能团,特别是杂环取代基的耐受性。该技术被应用于合成抗炎药法奈替唑以及与淋病奈瑟菌细菌中的肽基-tRNA水解酶(Pth)结合的含噻唑药物片段。
Synthetic approaches towards [18F]fluoro-DOG1, a potential radiotracer for the imaging of gastrointestinal stromal tumors
highly advantageous to have a radioligand able to bind the calcium-activated chloride channel DOG1, which is specific for GIST, and thus enable the sensitive, non-invasive and specific functional imaging of the disease by Positron Emission Tomography (PET). For this purpose, we developed different synthetic strategies towards a 4-phenylthiazole-2-amine-based labeling precursor that can be directly
