Iridium-Catalyzed Anti-Stereocontrolled Asymmetric Ring Opening of Azabicyclic Alkenes with Primary Aromatic Amines
摘要:
A novel iridium-catalyzed ring-opening reaction of azabicyclic alkenes with a variety of primary aromatic amines is reported, which afforded the corresponding 1,2-trans-diamine derivatives in high yields (up to 96%) with excellent enantioselectivities (up to 97% ee) under relatively mild conditions. The trans configuration of product 2b was confirmed by X-ray crystallography,

An efficient and highly chemo- and stereoselective copper-catalyzed hydroamination of oxa- and azabenzonorbornadienes with various pyrazole derivatives is described. This catalytic process is promoted by the presence of N-heterocyclic carbene ligands and KOt-Bu under mild and simple reaction conditions, and allows for the direct synthesis of new and versatile functionalized oxa(aza)benzonorbornyl pyrazoles
描述了一种有效且高度化学选择性和立体选择性的铜催化的氧杂和氮杂苯并降冰片二烯与各种吡唑衍生物的加氢胺化。N-杂环卡宾配体和 KO t -Bu 在温和和简单的反应条件下促进了这一催化过程,并允许从容易获得的氧杂(氮杂)直接合成新的多功能官能化氧杂(氮杂)苯并降冰片基吡唑。 )双环烯烃。该方法的合成效用通过将所得产物转化为吡唑基取代的萘来证明。
