Two guaiane-based sesquiterpenes from a Sinularia sp. soft coral
Investigation of a Sinularia sp. of soft coral has led to the identification of two known guaiane-based sesquiterpenes by evaluation of nuclear magnetic resonance spectroscopic data. The compounds are easily related either by biosynthetic dehydration across a methyl group and a tertiary alcoholic ca...
