Leucomycin A<SUB>3</SUB> (I) was oxidized with active manganese dioxide to dehydroleucomycin A<SUB>3</SUB> (II) which was identical with magnamycin B. Acid treatment of I yielded demycarosylleucomycin A<SUB>3</SUB> (VII), which was converted to a triacetate showing mass spectrum M<SUP>+</SUP> (m/e 725), and this observation confirmed the structure of I. The diene system of I was assumed to have a trans-trans configuration on the basis of its NMR spectrum, and a full structure of I was proposed with stereochemistry.
