The structure of a novel type of pentaene macrolide named lienomycin (I) was established by selected chemical transformations of I followed by MS examination of the products. This report provides evidence on the structure of the carbon skeleton of I and on the location of functionalities.
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.
