Abstract

Procedure for preparing penicillin derivatives, of interest as intermediaries for obtaining semi-synthetic penicillins, in particular 6-aminopenicillanic acid and derivatives, characterized by reacting a penicillin of formula: **(See formula)** or its salt, in which R1 can be an aliphatic or aromatic organic radical, with an organic derivative of tin of the formula **(See formula)** in which R2, R3 and R4 are the same or different organic radicals, aliphatic to aromatic and in which X is a reactive group, to obtain the corresponding organotin ester, by reacting the product obtained in the previous reaction with an agent of formation of imines in order to obtain the corresponding imino-compound, by transforming, if necessary, the imino-compound obtained into an imino-ether and by proceeding with the hydrolysis of the imine bond to obtain the corresponding organo-organic ester of 6-aminopenicillanic acid, and by proceeding with the hydrolysis of this ester, if desired, to obtain 6-aminopenicillanic acid in the free state.
