Abstract
Thie-o (2,3-b) pyridinecarboxylic acid derivs. (I; R1, R4, R5 = H, alkyl, R2 = H, alkyl, halogen and alkylene, producing alkyl-substituted or non-substituted 5 or 6 membered ring by binding R1 and R2), useful as broad spectrum antibiotic to gram positive and gram negative bacteria, and their salts were prepd. by cyclization of II (R1, R2 given, R3 = alkyl, Z = H, carboxyl), hydrolysis if needed, and alkylation of the resulting I'(R1, R2, R4 give-).
