WingPhos, a C2‐symmetric bisphosphorus ligand with a deep and well‐defined chiral pocket was developed. It has shown high efficiency in the rhodium‐catalyzed asymmetrichydrogenation of (E)‐β‐aryl‐N‐acetyl enamides, cyclic β‐aryl enamides, and heterocyclic β‐aryl enamides. A series of chiral β‐arylisopropylamines, 2‐aminotetralines, and 3‐aminochromans can be synthesized with excellent ee values (nbd=3
WingPhos是一种C 2对称的双磷配体,具有较深且定义明确的手性口袋。在(E)-β-芳基-N-乙酰基酰胺,环状β-芳基酰胺和杂环β-芳基酰胺的铑催化不对称氢化反应中显示出很高的效率。可以合成一系列具有良好ee值(nbd = 3,5-降冰片二烯; TON =周转数)的手性β-芳基异丙胺,2-氨基四氢呋喃和3-氨基苯并二氢吡喃。
