Abstract
Process for the preparation of penicillins and non-toxic salts thereof, characterized in that new penicillins of the general formula: under R1 and R2 or the group OR4 or SR4, where R4 is an alkyl, alkenyl, aryl, aralkyl or cycloalkyl group, are obtained by the reaction of 6-aminopenicillanic acid or a fermentation liquor containing 6-aminopenicillanic acid obtained by the development of a penicillin-producing mold in a nutrient medium, with or without subsequent partial purification, with an acid chloride, bromide or anhydride or mixed anhydride derived from a tri-substituted acetic acid of the general formula: (see formula) (Machine-translation by Google Translate, not legally binding)
