title: Two syntheses of FF-MAS.
abstract: [reaction: see text] Follicular fluid-meiosis activating sterol (FF-MAS) has been shown to be an efficient inducer of meiotic maturation. It can potentially be used for improvements of in vitro fertilization techniques. Two short synthesis of FF-MAS are presented in this article. Both syntheses are based on microbiological degradations of sterol side chains. FF-MAS can be synthesized in nine steps from commercially available starting materials by both routes.
