The present invention provides a method for preparing S-Bz-MAG3 as a precursor of contrast media. Thioglycolic acid and benzoyl chloride are taken for the thiol protection reaction. Next, N,N′-dicyclohexylcarbodiimide and N-hydroxysuccinimide are converte

Cysteine containing three functional groups, i.e. a carboxyl, sulfhydryl, and amino group, has been labelled with 99mTc(I) tricarbonyl precursor (2) in order to study the renal characteristics of the resulting 99mTc(I) tricarbonyl cy

Diverse thiol esters were synthesized in good to excellent yields (76-99%) by reactions of thiophenol, benzyl mercaptan, ethyl mercaptoacetate, and mercaptoacetic acid with N-acylbenzotriazoles under mild conditions. These results demonstrate the utility of N-acylbenzotriazoles as mild S-acylating agents, especially when the corresponding acid chlorides are not readily available.
