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 RuII 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
在2和3的存在下,通过C andC和C oneO一锅还原,将3-Arylidenechroman-4-ones和2-芳基-1-四氢
萘酮在dr和er中以高达99:1的比例氢化为顺式
苄醇。在不对称转移氢化动力学动力学拆分(ATH-DKR)条件下,Noyori–Ikariya型Ru II手性配合物和HCO 2 Na的含量为5 mol%。这些底物的氧化导致天然高纯
异黄烷酮二氢bonducellin及其
碳水化合物类似物的对映选择性合成。
