| Abstract: | Two new marine pyrazine derivatives, clavulazols A ( 4 ) and B ( 5 ), were isolated from ethyl acetate extract of the soft coral Clavularia viridis collected in Taiwan. The structures were determined on the basis of spectral analysis, especially 2D NMR as well as chemical conversion. |
