Under the optimal conditions, the annulated products 55 with a dihydronaphthalenamine skeleton were generated in up to 79% yield and 99% ee demonstrated in 29 examples. Further hydrogenation of 58aa generated product 71 with three chiral centers in good yield, enantioselectivity value, and diastereomer ratio (95% yield, 96% ee, d.r.> 20:1).一價銠金屬催化掌性雙環[2.2.1]雙烯配體鏡像選擇性不對稱串聯合環反應乙腈芳基硼酯掌性二氫萘胺化合物rhodium(I)-catalyzedchiral bicyclo[2.2.1]diene ligandsasymmetric cascade cyclizationenantioselectivearylboronic esterchiral dihydronaphthalenamine derivatives一價銠金屬催化具高鏡像選擇性之不對稱串聯反應:合成掌性二氫萘胺Highly Enantioselective Rhodium(I)-Catalyzed Asymmetric Cascade Reaction: Synthesis of Chiral Dihydronaphthalenaminesetd
