Die Struktur des Antibioticums Sparsomycin wurde zu (I) ermittelt.

A homologous series of straight-chain lincomycin 2-monoesters, comprised of both acyl and carbonate esters, was synthesized. Good antibacterial activity was observed with esters of chain lengths from C4 to C16. Esters with chain lengths from C12 to C16 are tasteless and highly active in vivo in mice infected with Staphylococcus aureus. The carbonate esters show essentially the same taste and bioactivity as the acyl esters. The long-chain lincomycin 2-esters appear to have the desired properties required for formulation as a tasteless pediatric preparation.

Tritylation of 3,4-O-anisylidene lincomycin (II) was found to give 7-O-trityl-3,4-O-anisplidene lincomycin (III), a key intermediate in the synthesis of lincomycin-2-monoesters. The structure of III was established by NMR. Phosphorylation of III with POCls in pyridine gave the resulting dichlorophosphate IV which after hydrolysis and treatment with 80% aqueous acetic acid (100°, 30 min.) gave lincomycin-2-phosphate (V). The water-soluble ester V is inactive in the plate antibacterial assay using S. lutea, although in uiuo V is as active as the parent compound lincomycin (I) in mice infected with S. aureus. V gave slightly higher blood levels than the parent compound I upon oral administration in dogs. The taste of V is less bitter than I.
