Penicillin esters, salts thereof and methods for their preparation

The invention relates to a new series of penicillin esters and salts thereof, to methods of their preparation and to intermediates in the production of the esters of the general formula STR1 in which R1 and R2 represent an alkyl radical having from 1 to 6 carbon atoms, a cycloalkyl or cycloalkylalkyl radical the cycloalkyl part having from 3 to 10 carbon atoms, or R1 and R2 together with the nitrogen atom represent a heterocyclic ring with from 4 to 8 carbon atoms; R3 represents radicals known from natural, biosynthetic, and semisynthetic penicillins; and pharmaceutically acceptable salts thereof. The new compounds are efficiently absorbed from the gastrointestinal tract and after the absorption they are rapidly transformed into the corresponding free penicillins and amidinopenicillanic acids, whereby a broad-spectrum infection can be combated.
