Improvements in the object of Patent No. 9101355 which relates to a "Procedure for obtaining new derivatives of platinum with aminopyrrolidines". It consists in the reaction of the compounds of general formula (II'), where R' is a linear alkyl containing from 2 to 12 carbon atoms and R'1 is a linear alkyl containing from 1 to 3 carbon atoms, with potassium tetrachloroplatinite. In the compounds which are the object of the present invention, of general formula (I'), R' and R'1 have the same meaning as in (II'). The compounds of the present invention are of pharmacological application because of their antitumoral activity. <IMAGE>
