Ru(III)-Catalyzed Cyclization of Arene-Alkene Substrates via Intramolecular Electrophilic Hydroarylation
摘要:
We herein report that RuCl3/AgOTf has proven to be a hydroarylation catalyst with an efficiency and scope superior to previously known methods. This catalyst demonstrated consistent performance with arene-ene substrates of diverse structural features, providing good to excellent yields of cyclization products (chromanes, tetralins, terpenoids, dihydrocoumarins).

ligands were designed and synthesized by a diastereoselective SNAr substitution of the corresponding sulfonyl pyridines. The ligands were successfully applied in the Ir-catalyzed asymmetrichydrogenation of unfunctionalizedalkenes with good enantioselectivities.
提出了富电子的2-取代的6-(苯磺酰基)吡啶的合成。通过相应的磺酰基吡啶的非对映选择性的S N Ar取代,设计和合成了一系列空气稳定的,可调节的P-手性吡啶基-二氢苯并恶唑磷配体。该配体已成功应用于具有良好对映选择性的Ir催化未官能化烯烃的不对称氢化反应。
