Abstract
1350772 Cephalosporin compounds MERCK & CO Inc 14 Jan 1972 [27 Jan 1971 17 June 1971 24 Aug 1971 29 Nov 1971] 3295/71 28522/71 39654/71 and 1829/72 Divided out of 1350772 Headings C2A and C2C 3 - Carbamoyloxymethyl - cephalosporin compounds having the general Formula (I) and the corresponding #<SP>2</SP> compounds, and salts and esters thereof, wherein R<SP>1</SP> is hydrogen or an acyl group and R 1 is hydrogen or methoxy, the said compounds being novel when R 1 is hydrogen, are prepared by reacting a corresponding 3- hydroxymethyl - cephalosporin compound, in which if necessary any isocyanate-reactive group other than the 3-hydroxymethyl group is suitably blocked, the bromo- or chloro-sulphonyl isocyanate and hydrolysing the product and if necessary removing any blocking group. The reaction is preferably effected in a polar organic solvent and the hydrolysis is carried out by treatment with aqueous acid. Monobenzhydryl phenylmalonyl chloride is prepared by treating phenylmalonic acid with diphenyldiazomethane followed by alkaline hydrolysis to give monobenzhydryl phenylmalonate which is converted to the acid chloride with oxalyl chloride. Benzyl alcohol is esterified with D-α-aminoadipic acid in the presence of c.H 2 SO 4 to give benzyl - D - 5 - amino - 5 - carboxypentanoate, which is then N-protected by reacting with tbutyloxycarbonyl azide in the presence of MgO giving benzyl - D - 5 - t - butyloxycarbonylamino - 5 - carboxypentanoate. The carboxyl group is protected by reacting the latter with 2,2,2 - trichloroethanol in pyridine, and the resulting benzyl D - 5 - t - butoxycarbonylamino - 5 - (2,2,2 - trichloroethoxy)carbonylpentanoate is catalytically hydrogenated to remove the benzyl ester group. The product, D- 5 - t - butoxy - carbonylamino - 5 - (2,2,2 - trichloroethoxy)carbonylpentanoic acid is reacted with oxalyl chloride to give the corresponding acid chloride. The cephalosporin compounds of Formula I and their #<SP>2</SP> isomers, salts and esters, wherein R<SP>1</SP> is an acyl group, have antibacterial activity and may be used with a suitable carrier, diluent or coating to provide pharmaceutical and disinfectant compositions.
