| Abstract: | ![]()
Two new highly oxidized formamidobisabolene sesquiterpenes ( 1 and 2 ), together with seven known related analogues ( 3 – 9 ), were isolated from a Hainan sponge Axinyssa variabilis. Their structures were determined by extensive 1D‐ and 2D‐NMR and MS spectra analyses, and by comparison of their spectroscopic data with those of the related model compounds. The plausible biosynthetic relationship between compounds 1 – 9 has also been described. |
