Abstract
Caprazene and caprazol could be synthesized by hydrolysis of a caprazamycin. There could be synthesized a caprazene-1′″-amide derivative of the formula (II)and a caprazene-1′″-ester derivative of the formula (III)from caprazene. Further, there could be synthesized a caprazol-1′″-amide derivative of the formula (V)and a caprazol-1′″-amide-3′″-ester derivative and a caprazol-3′″-ester derivative, etc. from caprazol. Furthermore, an imidazolidinone derivative could be synthesized from the ring-opened product of the 1,4-diazepinone ring of caprazol.The novel caprazene derivative, novel caprazol derivative and novel imidazolidinone derivative now synthesized exhibit excellent antibacterial activities against a variety of bacteria, including acid-fast bacteria.
