title: Neihumicin, a new cytotoxic antibiotic from Micromonospora neihuensis. II. Structural determination and total synthesis.
abstract: The structure of neihumicin, a new antibiotic isolated from the fermentation broth of Micromonospora neihuensis Wu, sp. nov., has been determined as (Z)-3,(Z)-6-dibenzylidene-2-methoxy-3,6-dihydropyrazin-5-one based upon spectral evidence and X-ray crystallographic analysis. Its total synthesis has also been achieved.
