Abstract
1,269,697. Silylated cephalosporin derivatives. ELI LILLY & CO. 22 Aug., 1969 [23 Aug., 1968], No. 42066/69. Heading C2A. [Also in Division C3] Novel silylated cephalosporin derivatives of Formula VI wherein R<SP>11</SP> is hydrogen or acetoxy, and R<SP>1</SP>, R<SP>2</SP> and R<SP>3</SP> are each hydrogen or a C 1 to C 8 hydrocarbon radical free from aliphatic unsaturation, with not more than two of R<SP>1</SP> , R<SP>2</SP> and R<SP>3</SP> bonded to the same silicon atom being hydrogen, and R<SP>10</SP> is hydrogen or the group: are prepared by reacting 7-aminocephalosporanic acid or 7-amino-desacetoxycephalosporanic acid or a salt thereof, with a mono- or bissilylamide of one of the Formulµ I to V wherein R<SP>1</SP>, R<SP>2</SP> and R<SP>3</SP> are as defined above; R<SP>5</SP> and R<SP>9</SP> are each hydrogen or C 1 to C 8 hydrocarbon free from aliphatic unsaturation, R<SP>8</SP> is C 1 to C 8 hydrocarbon free from aliphatic unsaturation; each of R<SP>4</SP>, R<SP>6</SP> and R<SP>7</SP> is hydrogen or C 1 to C 8 hydrocarbon free from aliphatic unsaturation, or R<SP>6</SP> and R<SP>7</SP> together with the common nitrogen complete a heterocyclic ring containing 5 to 6 ring-forming atoms, one of which can be oxygen para to the nitrogen, or 4 to 6 ring-forming carbons provided that R<SP>6</SP> and R<SP>7</SP> together contain not more than 18 carbons and that if R<SP>6</SP> is alkyl with tert. carbon bonded to the nitrogen then R<SP>7</SP> is hydrogen; or R<SP>4</SP> and R<SP>6</SP> together with the attached nitrogens and the carbonyl group form a heterocyclic ring containing 5 to 6 ring-forming atoms and 2 to 3 methylene ring-forming carbon atoms; and Y is a C 3 to C 18 alkylene group with a 3 to 5 carbon chain between the nitrogen and the carbonyl group to which Y is bonded, the reaction being effected in an anhydrous aprotic solvent at - 25 to +50 C. The invention includes a composition comprising (a) a compound of Formula VI above, (b) a silylamide of one of Formulµ I to V above and (c) an anhydrous solvent for (a) and (b) of which the molecules do not contain Zerewitinoff hydrogen. The silylated cephalosporins may be converted to known antibiotically active cephalosporins by reacting with an appropriate acylating agent to give the corresponding N-acylated silyl ester which is treated with a C 1 to C 6 alkanol to give the required cephalosporin which is recovered from the solution preferably as the Na or K salt. Cephalothin, cephaloglycin and cephalexin are prepared in this way.
