摘要:
A new marine pyrazine congener, clavulazine (2), was obtained from the polar portion of the MeOH extract of the Okinawan soft coral Clavularia viridis as its acetate (1). The structure of 2 was determined on the basis of spectral analysis and chemical conversion. The absolute configuration of 2 was unambigously determined by X-Ray crystallographic analysis on the p-bromobenzoate (3).
