Popis: | The synthesis of the first dithieno[2,3-b : 2′,3′-e]-1,4-thiazine is described, this compound was prepared by condensation of 3-thiophenethiol with methyl 2-bromo-3-nitrothiophene-5-carboxylate followed by reduction, acylation, bromination with NBS and ringclosure with Cu, K2CO3 in nitrobenzene. A thieno-1,4-benzothiazine was prepared in the same way. These compounds were synthesized in order to study the suggested correlation between charge-transfer complexes vs. physiological activity. |
