AbstractPalladium‐catalyzed asymmetric [4+3] cycloadditions of indene‐2‐carbaldehydes and 4‐vinyl benzoxazinanones proceeded smoothly in the presence of chiral phosphine ligands to give the corresponding functionalized 5H‐benzo[b]azepines (26 examples, 60% to 89% yield, 88:12 to 95.5:4.5 er) under mild conditions.magnified image

A Cu-catalyzed enantioselective desymmetrizing ring-opening reaction of six-membered cyclic diaryliodonium salts with carboxylic acids or thioacids is reported for the facile access to chiral diarylmethanes. A Cu/[cyclopropyl bis(oxazoline)] catalyst well discriminates two C-I bonds of prochiral cyclic diaryliodonium salts. A stereochemical model was proposed to rationalize the stereochemical outcome
据报道,六元环状二芳基碘鎓盐与羧酸或硫代酸的 Cu 催化对映选择性去对称开环反应可轻松获得手性二芳基甲烷。Cu/[环丙基双(恶唑啉)]催化剂很好地区分了前手性环状二芳基碘鎓盐的两个CI键。基于环状二芳基碘鎓盐的晶体结构,提出了立体化学模型来合理化立体化学结果。
