Abstract
Process for the manufacture of penicillins of the general formula I C8H10O3NS-NH-z1-R1 (X-R2) n, in which Z1 represents a CO- or SO2 group, R1 an optionally substituted aliphatic bivalent moiety, X a direct bond, oxygen or sulfur, and R2 an organic residue, preferably an aliphatic, araliphatic, aromatic, or heteroxyclic residue, which may be optionally substituted, and n = 1 or 2, respectively, of salts of these penicillins, characterized in that the process is carried out as fermentation under addition of precursor compounds, and an acid halide is added as the precursor compound.
