摘要：

3-Arylidenechroman-4-ones and 2-arylidene-1-tetralones are hydrogenated to cis-benzylic alcohols in dr's and er's up to 99:1 via a C=C and C=O one-pot reduction in the presence of 2-5 mol % Noyori-Ikariya-type Ru-II chiral complexes and HCO2Na as a hydrogen source under asymmetric transfer hydrogenation-dynamic kinetic resolution (ATH-DKR) conditions. The oxidation of theses substrates resulted in the enantioselective synthesis of the natural homoisoflavanone dihydrobonducellin and its carba-analogues.
