The structure of the potent nematicide omphalotin, isolated from the mycelia of the basidiomycete Omphalotus olearius, was determined by spectroscopic techniques. Omphalotin is a cyclic dodecapeptide consisting of 3 glycine, 5 valine, 3 isoleucine and 1 tryptophane, and 9 of the 12 a-nitrogens are methylated. HMBC and NOESY correlations between the N-methyl groups and the a-carbonda-hydrogens established the sequence of amino acids.
