    Synthesis of the aglycone of 26-O-deacetyl pavoninin-5
    摘要:
    The aglycone of 26-O-deacetyl pavoninin-5, (25R)-cholest-5-en-3beta,15alpha,26-triol, 5a, was synthesized in 10 steps in 17% overall yield from diosgenin, 3. Removing mercury from the Clemmensen reduction of diosgenin 3, gave a higher yield of (25R)-cholest-5-en-3beta,16beta,26-triol, 4, by a method, that is also more environmentally friendly. Attempted methods for the transposition of the C-16beta hydroxyl to the 15alpha position are described. A successful method for this transposition via the 15alpha-hydroxy-16-ketone, 13, using the Barton deoxygenation reaction on the 16-alcohol, 15, is reported.

    We describe the stereoselective transformation of diosgenin (4a) to (25R)-Δ4-dafachronic acid (1a), (25R)-Δ7-dafachronic acid (2a), and (25R)-cholestenoic acid (3a), which represent potential ligands for the hormonal receptor DAF-12 in Caenorhabditis elegans. Key-steps of our synthetic approach are a modified Clemmensen reduction of diosgenin (4a) and a double bond shift from the 5,6- to the 7,8-position. In the 25R-series, the Δ7-dafachronic acid 2a exhibits the highest hormonal activity.
    我们描述了二氢甾烯(4a)选择性转化为(25R)-Δ4-达法喹酸(1a)、(25R)-Δ7-达法喹酸(2a)和(25R)-胆甾烷酸(3a)的过程,这些化合物代表了线虫(Caenorhabditis elegans)激素受体DAF-12的潜在配体。我们合成方法的关键步骤是对二氢甾烯(4a)的改进Clemmensen还原和双键从5,6位转移到7,8位。在25R系列中,Δ7-达法喹酸2a显示出最高的激素活性。
