    • LOCATED IN THE 7(S)-position when R1 and R2 are taken independently, A represents hydrogen or hydroxyl, B represents hydrogen or hydroxyalkyl, n is the integer 0 when B is hydroxyalkyl and n is an integer of 0 to 1, inclusive, when B is hydrogen, X is oxygen or sulfur, D is the acyl radical of a lower hydrocarbon carboxylic acid; R4 is lower alkyl and Y is carboxacyl or hydrogen. Disclosed also are methods of making and using the novel compounds of the invention, which are useful intermediates in the chemical synthesis of useful antibacterial lincomycin analogs. Certain of the compounds of the invention are also active as antibacterial agents.

      WHEREIN Z and R5 are as defined above; R3 is hydrogen when R1 and R2 are taken together and is a monovalent thio group of formula:

      WHEREIN Z is hydrogen, lower alkyl or a protective group removable by hydrogenolysis; R5 is lower alkyl; R1 and R2 when together are the divalent group;

      WHEREIN Ac is carboxacyl or an acyl group of formula:

      ARE DISCLOSED, WHEREIN R1 taken independently is hydrogen; R2 taken independently is the moiety
