In a preliminary publication (1) we reported on the partial structure of lucensomycin, a tetraenoid macrocyclic antibiotic isolated from submerged cultures of Streptomyces lucensis. On the baeis of the experiments summarized below, the following structural fra@aents were shown to be present in the antibiotic : Hcoo, -cooH %%' )'O 2 or more OH Ozonolysis of lucensomycin gave 2-heptenal (III), end alkaline treatment under mild conditions afforded 13-hydroxy-2,4,6,8,10-heptadecapentaenal.
