    摘要: 23-De(mycinosyloxy)tylosin (DMOT) which has the formula: ##STR1## 20-dihydro-DMOT, specified acyl ester derivatives, and the acid addition salts thereof are useful antibacterial agents. New methods of making 23-deoxy-5-O-mycaminosyltylonolide (DOMT) and 20-dihydro-DOMT by mild acid hydrolysis of DMOT and 20-dihydro-DMOT, respectively, are included.
