C-Aminoimidoylation and C-Thiocarbamoylation of Esters, Sulfones, and Ketones
摘要:
Esters, sulfones, and ketones were C-aminoimidoylated and C-thiocarbamoylated by benzotriazole-1-carboxamidines 8a-g and 1-(alkyl-or-arylthiocarbamoyl)benzotriazoles 9a-i, respectively. The present work represents the first systematic approach to these compound classes, the few previously known examples of which were obtained by diverse approaches.
Synthesis, characterization and blood cell labelling evaluation of new 99mTc nitrido radiopharmaceuticals with thioamide [R1C(=S)NHR2] derivatives
摘要:
The synthesis of a series of new Tc-99m-thioamide complexes with the [Tc=N](2+) nitrido core, in which the thioamide ligand substituents were varied to include different lengths of aliphatic alkyl chains or a phenyl group is reported TLC analysis shows that the complexes are neutral and lipophilic compounds. The Tc-99m complexes have a low blood cell labelling efficiency in whole blood compared to the reference complex of dithiocarbamate (TcN)-Tc-99m(Et(EtO)NCS2)(2).
