title: The structure of lienomycin, a pentaene macrolide antitumor antibiotic. II. The location of the pentaene chromophore and of six isolated double bonds. The complete structure of the antibiotic.
abstract: The locations of the isolated double bonds and of the pentaene chromophore in lienomycin (I) were established by chemical degradation of I followed by MS and 1H NMR examination of the products. The complete structure of the antibiotic is proposed.
