This invention relates generally to methods for preparing certain bile acids from non-mammalian sourced starting materials as well as to synthetic bile acids and compositions comprising such acids wherein the acids are characterized by a different C

population than naturally occurring bile acids as well as being free from any mammalian pathogens. This invention is also directed to the synthesis of intermediates useful in the synthesis of such bile acids. Accordingly, the C ring of the steroidal scaffold is oxidized to provide a synthetic route and intermediates to DCA. This invention also provides synthetic methods for preparing deoxycholic acid or a salt thereof starting from aromatic steroids such as estrogen, equilenin, and derivatives thereof. This invention is also directed to intermediates such as 12-oxo or delta-9,11-ene steroids as well as novel processes for their preparation. In preferred embodiments, bile acids are provided herein which have substituents on the B-ring and/or D-ring side chain and optionally on the hydroxy group of the A-ring.
本发明涉及从非哺乳动物来源的起始材料制备某些胆汁酸的方法,以及合成胆汁酸和包含这些酸的组合物,其中这些酸的特征是具有与自然存在的胆汁酸不同的C14种群,并且不含任何哺乳动物病原体。本发明还涉及合成在合成这种胆汁酸中有用的中间体。因此,甾体骨架的C环被氧化以提供合成路线和到DCA的中间体。本发明还提供了用芳香族类固醇(如雌激素、雌烯酮及其衍生物)起始制备脱氧胆酸或其盐的合成方法。本发明还涉及12-氧代或δ-9,11-烯类固醇等中间体以及其制备的新型过程。在首选实施例中,本发明提供了具有B环和/或D环侧链以及可选地具有A环羟基上取代基的胆汁酸。
