    摘要: Derivatives of oleandomycin, its 11-trimethylsilyl ether and 11-trimethylsilyl-2'-alkanoyl esters and processes for preparation thereof wherein the L-oleandrosyl moiety is modified at the 4"-position to provide derivatives thereof wherein said moiety has formula ##STR1## wherein A and B when taken together are .dbd.CHX wherein X is H, --CN, --COOR.sub.3, --SR.sub.3 ', --S(O)R.sub.3 ', --S(O).sub.2 R.sub.3 ' or ##STR2## A when taken individually is hydrogen; B when taken individually is --CHO or --CH.sub.2 Z wherein Z is hydrogen, --OR.sub.3, --COOR.sub.3, --SR.sub.3 ', --S(O)R.sub.3 ', --S(O).sub.2 R.sub.3 ', --CN or --(CH.sub.2).sub.n --NR.sub.5 R.sub.6 ;R.sub.3 is hydrogen, ##STR3## R.sub.3 ' is (C.sub.1-4)alkyl or ##STR4## R.sub.4 is hydrogen, chloro, bromo, (C.sub.1-4)alkyl or (C.sub.1-4)alkoxy; R.sub.5 is hydrogen or ##STR5## R.sub.6 is hydrogen, --COCH.sub.3, ##STR6## R.sub.5 and R.sub.6 when taken together with the nitrogen to which they are attached are phthalimido;n is 0 or 1;or a pharmaceutically acceptable acid addition salt thereof of a compound wherein B is --CHO or --CH.sub.2 Z.The compounds are antibacterial agents. Additionally, those compounds wherein the oleandrosyl moiety is of formula (b), or of formula (a) wherein A is hydrogen and B is CHO, and those wherein A and B when taken together are .dbd.CH--X, are useful as intermediates for formula (a) derivatives wherein A is hydrogen and B is --CH.sub.2 Z.
