Give me a P: An asymmetric intramolecular Rh‐catalyzed hydroacylation reaction of pent‐4‐enals for the preparation of functionalized cyclopentanones in good yield and high enantioselectivity is described (see scheme, DCE=dichloroethane). This process uses rhodium complexes featuring novel modular phosphoramidite–alkene ligands and achiral phosphine coligands.
给我一个P:描述了戊4-烯醛的不对称分子内Rh催化加氢酰化反应,以高收率和高对映选择性制备官能化的环戊酮(参见方案,DCE =二氯乙烷)。该工艺使用具有新型模块化亚磷酰胺-烯烃配体和非手性膦大分子配体的铑配合物。
