Abstract
1,053,818. Penicillins. BEECHAM GROUP Ltd. Nov. 26, 1965 [Dec. 3, 1964], No. 49123/64. Heading C2A. The invention relates to penicillins of general formula and non-toxic salts thereof, where R is an alkyl, aralkyl, aryl or heterocyclic group which may be substituted and R<SP>1</SP> is any one of the groups defined under R or an alkoxy, aralkoxy, aryloxy, amino or substituted amino group, e.g. 6 - (D - α - oxamamido - α - phenylacetamido) penicillanic acid and 6-(D-α-ethoxyoxalamido- α-phenyl acetamido) penicillanic acid. The penicillins are produced by reacting 6-aminopenicillanic acid or a salt thereof with a reactive derivative of an acid of general formula wherein R and R<SP>1</SP> have the above meanings. Alternatively, an α-amino penicillin of general formula may be treated with a reactive derivative of an acid of formula R<SP>1</SP>CO.COOH, where R and R<SP>1</SP> have the above meanings.
