    • Lincomycin is formed by tosylating methyl 1-thio- Alpha -Dgalacto-octopyranoside to form methyl 6-O-(p-toluenesulfonyl)-1thio- Alpha -D-galactopyranoside, acylating the resulting compound to form the peracylate, replacing the tosyl group with iodine to form peracylated methyl 6-deoxy-6-iodo-1-thio- Alpha D-galactopyranoside, replacing the iodo group by a nitro group to form peracylated methyl 6-deoxy-6-nitro-1-thio- Alpha -Dgalactopyranoside, treating the latter with acetaldehyde and sodium methoxide to form methyl 6-deamino-6-nitro- Alpha thiolincosaminide, reducing the latter with lithium aluminum hydride to form methyl Alpha -thiolincosaminide, and acylating the latter with trans-1-methyl-4-propyl-L-2-pyrrolidinecarboxylic acid. By substituting other aldehydes and/or other 1-thio- Alpha -D-galactopyranosides, analogs of lincomycin are obtained.

    • THIS INVENTION RELATES TO A NOVEL PROCESS FOR THE MANUFACTURE OF LINCOMYCIN-3-MONOACYLATE COMPOUNDS, INCLUDING NOVEL 7-HALOGENATED LINCOMYCIN-3-MONOACYLATE COMPOUNDS, SELECTED FROM THE GROUP CONSISTING OF THE FREE BASES AND ACID ADDITION SALTS OF THE FORMULA:

      2-RS-,3,5-DI-HO-,3-AC-O-,6-((4-R1,1-R2-PYRROLIDIN-3-YL)-

      CO-NH-CH(-CH(-X)-CH3))-TETRAHYDROPYRAN

      WHEREIN R IS ALKYL OF 1 TO 6 CARBON ATOMS, INCLUSIVE; R1 IS ALKYL OF 2 TO 8 CARBON ATOMS, INCLUSIVE; R2 IS ALKYL OF 1 TO 8 CARBON ATOMS, INCLUSIVE, OR HYDROGEN; X IS HYDROXY, CHLORINE, BROMINE OR IODINE; AND AC IS THE ACYL RADICAL OF A HYDROCARBON CARBOXYLIC ACID CONTAINING 1 TO 18 CARBON ATOMS, INCLUSIVE. IN THE ABOVE FORMULA I, THE VERTICAL WAVY LINE F IS USED TO INDICATE THAT THE GROUP R1 CAN BE IN THE CIS POSITION (BELOW THE PLANE OF THE RING) OF IN THE TRANS POSITION (ABOVE THE PLANE OF THE RING), WITH RESPECT TO THE CARBONYL GROUP. THE HORIZONTAL WAVY LINE $ IS USED TO INDICATE THAT BOTH EPIMERS ARE TO BE INCLUDED IN THE GROUP, THE 7(R) (OR D-ERYTHRO) CONFIGURATION AND THE 7(S) (OR L-THREO) CONFIGURATION. THESE LINCOMYCIN-3-MONOACYLATE COMPOUNDS CAN BE USED AS ANTIBACTERIAL AGENTS, FOR EXAMPLE TO INHIBIT THE GROWTH OF STAPHYLOCOCCUS AUREUS AND SARCINA LUTEA ON DENTAL AND MEDICAL EQUIPMENT CONTAMINATED WITH THESE ORGANISMS. THE NOVEL 7-HALOGENATED 3-MONOACYLATE ESTERS ARE PARTICULARLY ADVANTAGEOUS IN HAVING GREATER ANTIBACTERIAL ACTIVITY THAN THE 7-HYDROXY ESTERS. THE NOVEL PROCESS FOR SELECTIVE 3-MONOACYLATION OF LINCOMYCIN COMPOUNDS OF THIS INVENTION COMPRISES MIXING A SOLUTION OF THE LINCOMYCIN COMPOUND OR ITS ACID ADDITION SALT WITH THE ACID ANHYDRIDE OR ACYL HALIDE OF A HYDROCARBON CARBOXYLIC ACID AND A STERICALLY HINDERED STRONGLY BASIC TERTIARY AMINE AND REACTING UNDER MILD CONDITIONS.
