By the fermentation of Streptomyces cinereocrocatus, 2’-propoxy analogs of (-)- and (+)-dehydrogriseofulvin were both converted into the corresponding analog of (+)-griseofulvin and the same treatment of (+)-2’-demethoxydehydrogriseofulvin afforded (+)-2’-demethoxygriseofulvin and (+)- and (-)-2’-demethoxy-2’,3’-dihydrodehydrogriseofulvin, indicating that the (+)-substrates were isomerized into the corresponding (-)-enantiomers and subsequently transformed to the reduction products.
