  Unprecedented Effects of Achiral Oxazolidinones on Enantioselective Radical-Mediated Conjugate Additions Using a Chiral Zinc Triflate

  摘要：

  [GRAPHICS]A role of achiral oxazolidinones to enhance the enantioselectivity in reactions of N-cinnamoyloxazolidinones with alkyl radicals promoted by a chiral Lewis acid Is described. Efficient enantioselective radical-mediated conjugate additions of N-cinnamoyloxazolidinone can be realized by use of a chiral zinc triflate generated from a readily prepared chiral bisoxazoline and an achiral oxazolidinone. The NH moiety of achiral oxazolidinones is found to be necessary to enhance the enantioselectivity.

  Asymmetric Michael additions to .alpha.,.beta.-unsaturated oxazolines. An efficient preparation of chiral .beta.,.beta.-disubstituted propionaldehydes

  摘要：

  A short stereoselective route to a variety of chiral, nonracemic alpha,beta-unsaturated oxazolines derived from (S)-tert-leucinol is described. Addition of organolithium reagents to this chiral oxazoline occurs in a Michael fashion, giving rise to adducts with high diastereoselectivity. Reductive cleavage of the oxazoline leaves the beta,beta-disubstituted aldehydes in > 93% ee. This process represents a significant improvement in one of the earliest asymmetric conjugate additions first reported in 1975.

• Copper-Catalyzed Asymmetric Allylic Substitution of Allyl Phosphates with Aryl- and Alkenylboronates
  作者：Ryo Shintani、Keishi Takatsu、Momotaro Takeda、Tamio Hayashi

  日期：2011.9.5

  The asymmetric allylic substitution of allyl phosphates with aryl‐ and alkenylboronates catalyzed by a copper/N‐heterocyclic carbene complex was developed and the γ‐substitution products were obtained with high enantioselectivity (see scheme). To account for the observed influence of the reaction parameters a possible catalytic cycle for this process was proposed.

  γ-disubstituted and β,γ-disubstituted allylic alcohols were prepared and successfully hydrogenated using suitable N,P-based Ir complexes. High yields and excellent enantioselectivities were obtained for most of the substrates studied. This investigation also revealed the effect of the acidity of the N,P–Ir-complexes on the acid-sensitive allylic alcohols. DFT ΔpKa calculations were used to explain the effect of

High γ-selectivity was realized when either the aryl group of the Grignard reagent or the aryl group on the N-substituent of the carbene ligand was electron-deficient or when either the carbene ligand or allylic bromide was bulky.
