Abstract

"REDUçãO ESTEREOSPECìFICA DE SAPOGEN-3-ONAS". A presente invenção refere-se a um método para preparar estereospecificamente uma sapogenina esteroidal ou um derivado desta, mediante redução de uma 3-ceto,5<225>-H sapogenina esteroidal com um organoborano bloqueado ou um hidreto de organoalumínio. Uma 3<225>-hidróxi,5<225>-H sapogenina esteroidal ou derivado desta poderá ser preparada mediante redução da 3-ceto,5<225>-H sapogenina esteroidal usando como agente redutor um reagente de organoborano relativamente altamente bloqueado, ou por meio de inversão S~ N~2 de uma 3<244>-hidróxi,5<225>-H sapogenina esteroidal ou derivado desta. O hidreto de organoalumínio poderá ser usado para preparar uma 3a,5<225>-H sapogenina esteroidal ou derivado desta. A invenção proporciona uma rota conveniente para sapogeninas esteroidais úteis tais como sarsassapogenina, epissarsassapogenina, esmilagenina, epiesmilagenina e ésteres destas, a partir de materiais de partida prontamente disponíveis ou facilmente preparáveis (por exemplo, diosgenona, preparável a partir de diosgenina).
