    DOI:10.1039/p19960000295
    日期:——
    Brassinolide has been synthesized from stigmasterol in an overall yield of 7%. The key step in the synthesis is aldol condensation of 2α,3α-isopropylidenedioxy-6-oxo-23,24-dinor-5α-cholan-22-al with 3-isopropylbut-2-enolide carried out at – 78 °C, which gives a product with 22R,23R stereochemistry in high yield. Catalytic hydrogenation of this product is highly stereoselective leading to the desired
    从豆甾醇中合成油菜素内酯,总收率为7%。合成的关键步骤是在– 78°C下进行2α,3α-异丙基二烯二氧基-6-oxo-23,24-dinor-5α-cholan-22-al与3-异丙基丁-2-烯内酯的醇醛缩合反应。以高收率得到具有22 R,23 R立体化学的产物。该产物的催化氢化是高度立体选择性的,导致在中间体中所需的24 S立体化学,该中间体很容易转化为油菜素内酯。

    From castasterone (10), 6a-carbabrassinolide (2) was synthesized via a highly regioselective B-ring homologation with trimethylsilyldiazomethane and boron trifluoride etherate. A preliminary experiment using a simple 6-oxo-steroid (3) revealed that the actual products of this homologation reaction were α-trimethylsilyl ketones (4) and (5), which were converted to 6 (79%) and 7 (7.2%) by acid treatment
