A Concise Approach to Oxo-Dehydrorotenoid by Direct Lactonization and the Total Syntheses of Stemonone, Rotenonone, 6-Oxo-dehydroelliptone, and 6-Oxo-6a,12a-dehydrodeguelin
An approach to construct the oxo‐dehydrorotenoids via direct lactonization of isoflavone‐2‐carboxylic acids is reported. The application of this method for the first total syntheses of the natural products, stemonone, 6‐oxo‐dehydroelliptone, rotenonone, and 6‐oxo‐6a,12a‐dehydrodeguelin, are demonstrated. The series of oxo‐dehydrorotenoids was also evaluated for their biological activities.

(R,R)-RuII-catalysts promoted the one-pot C=C/C=O bonds reduction of isoflavones through ATH-DKR. Ten cis-3-phenylchroman-4-ols were selectively obtained (>20 : 1 dr) in good yields (up to 86 %) and excellent er (up to >99 : 1). Due to the neutral conditions employed, isoflavones with different substituents at the 2’-position of B-ring (H, OH, OMe and Br) were successfully reduced. Synthetic applications
( R , R )-Ru II -催化剂通过 ATH-DKR 促进异黄酮的一锅 C=C/C=O 键还原。以良好的产率(高达 86%)和优异的 er(高达 >99:1)选择性地获得了10 种顺式-3-苯基色满-4-醇(>20:1 dr)。由于采用中性条件,在 B 环(H、OH、OMe 和 Br)的 2' 位具有不同取代基的异黄酮被成功还原。还展示了这些手性产品的合成应用。
