  Catalytic Asymmetric Conjugate Addition of Dialkylzinc Reagents to β-Aryl-α,β-unsaturated N-2,4,6-Triisopropylphenylsulfonylaldimines with Use of N-Boc-l-Val-Connected Amidophosphane-Copper(I) Catalyst

  摘要：

  Asymmetric conjugate addition of dialkylzinc to alpha,beta-unsaturated N-2,4,6-triisopropylphenylsulfonylaldimines 9 was catalyzed by 5 mol % N-BOC-L-valine-connected amidophosphane 5a-Cu-(MeCN)(4)BF4 in the presence of 4 Angstrom MS in toluene to afford, after hydrolysis of an imine to an aldehyde through a short alumina column and reduction with sodium borohydride, the corresponding beta-alkylated alkanols 10 with 67-91% ee in reasonably high yields.
