ABSTRACT:
23-Ester derivatives of demycinosyltylosin (DMT) of the formula: ##STR1## wherein R is selected from hydrogen, optionally substituted C.sub.1 -C.sub.5 -alkanoyl or optionally substituted benzoyl, phenylacetyl, or phenylpropionyl; and R.sup.1 is an acyl group selected from: ##STR2## p is 0 or 1; m and n are integers from 0 to 4; R.sup.2 is hydrogen, halo, C.sub.1 -C.sub.4 -alkyl, C.sub.3 -C.sub.8 -cycloalkyl, phenyl, C.sub.5 -C.sub.8 -cycloalkenyl, naphthyl, indenyl, tetralinyl, decalinyl, adamantyl, cinnoxacinyl, a monocyclic heterocyclic ring system comprising 3 to 8 atoms or a bicyclic heterocyclic ring system comprising 6 to 11 atoms, provided that at least 1 atom of the ring system is carbon and at least 1 atom of the ring system is a heteroatom selected from O, N, and S; and wherein R.sup.2 and the connecting alkyl groups --(CH.sub.2).sub.m -- and --(CH.sub.2).sub.n -- are optionally substituted by one or two halo, methyl, ethyl, methoxy, amino, N-protected-amino, methylamino, dimethylamino, nitro, acetoxy, acetamido, azido, carbomethoxy, carboxamido, cyano, or hydroxyl groups, provided that, if the substituent is other than halo or alkyl, there can be no more than one substituent on any connecting --CH.sub.2 -- group; X is O, S, --NH--, --N(CH.sub.3)--, --C.tbd.C--, --CH.dbd.CH--, --C(CH.sub.3).dbd.CH--, --CH.dbd.C(CH.sub.3)-- or --C(CH.sub.3).dbd.C(CH.sub.3)--; R.sup.3 and R.sup.4 are C.sub.1 -C.sub.5 -alkyl or optionally substituted phenyl or benzyl; and salts thereof are useful antibiotics or intermediates to antibiotics.
