Structural Elucidation of Niphimycin, Part 3. Identity of Scopafungin and Niphimycin I. Position of the Malonyl Residue of Niphimycin and Copiamycin The identity of scopafungin with niphimycin I was proven by spectroscopic and chromatographic methods and by common degradation products. The position of the malonyl residue in niphimycin I ( 9 ) and in copiamycin ( 14 ) was deduced by 1 H‐NMR spin‐decoupling experiments of a degradation product ( 10 ).
