Abstract

Fremgangsmåter for syntesen av tigogenin-/3-O-cellobiosid- heptaalkanoat som er et mellomprodukt for det kjente hypokole- esterolemiske midlet tigogenin-/3-cellobiosid. Fremgangsmåten innbefatter omsetning av a-cellobiosylbromid-heptaalkanoat og /3-tigogenin i nærvær av sinkfluorid eller sinkcyanid under slike betingelser at man får dannet nevnte tigogenyl-£-0- cellobiosid-heptaalkanoat. Det er også beskrevet analoge fremgangsmåter for fremstilling av hecogenin-/3-0-cellobiosid- heptaalkanoat, ll-ketotigogenin-/3-0-cellobiosid-heptaalkanoat og diosgenin-/3-O-cellobiosid-heptaalkanoat. Fremgangsmåten gir både høy /3-anomer selektivitet og høyt utbytte.
