Abstract
Starting from the chiral compound 1, (R)‐(+)‐2‐methyl‐1,4‐[^14^C]butanediamine 7 was synthesized in a sequence of reactions in which ^14^C‐label was introduce using label potassium cyanide. Compound 7 was reacted with potassium tetraiodoplatinate and silver 1,1‐cyclobutanedicarboxylate to make the title compound {[SP‐4‐3‐(R)]‐1,1‐cyclobutanedicarboxylato(2)platinum} 11.
