One stereocenter makes all the difference: The synthesis and biological evaluation of 17-epi-cortistatin A is reported from a common intermediate used to procure natural cortistatin A. The synthesis features a unique stereocontrolled Raney-Ni reduction process that can be employed to reliably produce both alpha- and beta-configured D-ring aryl steroids. Biological evaluations of these "cortalogs" are reported for the first time.
报道了从用于制备天然皮质抑素A的常见中间体合成17-表-皮质抑素A及其生物学评价。该合成具有独特的立体控制阮内镍还原过程,可用于可靠地制备α-和β-构型的D环芳基甾体。首次报道了这些“皮质类似物”的生物学评价。
