标题:Synthesis And Resolution Of 1-(2-Diphenylphosphino-1-Naphthyl)Isoquinoline; A Pn Chelating Ligand For Asymmetric Catalysis.
摘要:A Multistep Synthesis Resulting In A Good Yield Of The Title Compound Has Been Developed Based On The Pd-Catalysed Coupling Of 1-Chloroisoquinoline And 2-Methoxy-1-Naphthylboronic Acid (5). The Product Is Converted Into The Corresponding Tfifluoromethanesulphonate (10) By Successive Demethylation And Treatment With (Cf3Co)2O,Followed By A Further Pd-Catalysed Coupling With Ph2P(O)H. The Resulting Phosphine Oxide (11) Was Cleanly Reduced With Hsicl3. Resolution Of The Phosphinamine (4) Was Carried Out With The Pd Complex Derived From (R)-(+)-Dimethyl(1-(1-Naphthyl)Ethyl)Amine And Pdcl2; The Diastereomers Were Of Different Stabilities And Solubilities And Were Therefore Readily Separated. The Resolved Phosphinamine,[alpha]D22 +/-153 (C = 1,Chcl3),Was Enantiomerically Stable On Heating To 65-Degrees-C For 24H. X-Ray Crystal Structures Of The Adduct (16) And The Pd Dimer (7) Isolated During The Initial Coupling Reaction Are Presented.
