The biohydroxylation of stemodin and stemodinone by Beauveria bassiana ATCC 7159 gave exclusively 2alpha,13,18-trihydroxystemodane and 13,18-dihydroxystemodan-2-one respectively. Stemarin was converted to the novel 1beta,13,19-trihydroxystemarane and 13-hydroxystemarane-19-carboxylic acid. The synthesis and biotransformation of various derivatives of stemodin have also been studied.
