  A pineno-salen type catalyst for the enantioselective Nozaki–Hiyama–Kishi reaction

  摘要：

  A new class of pineno-salen type ligands 10, 11, 17, 20, 23, and 24 has been developed. The catalyst formed from chromium(II)-10 promotes the enantioselective Nozaki-Hiyama-Kishi allylation of alkyl and aryl aldehydes using allyl bromide. Notably, the asymmetric addition of vinyl halide to benzaldehyde was achieved with 24% ee. (C) 2012 Elsevier Ltd. All rights reserved.

  A phenylalanine derived chiral amide is developed that serves as an effective organocatalyst for the reaction of allyltrichlorosilane with aryl, hetero-aryl and α,β-unsaturated aldehydes to afford the desired homoallylic alcohols in good yield (up to 90%) and high enantioselectivity (up to 99%). The experimental results and DFT calculations suggest that para substituted aromatic aldehydes as substrate show higher ee in the product than their ortho/meta counterparts. The 1H and 13C NMR spectra study corroborated the calculated results. The chiral organocatalyst can be easily synthesized from optically pure phenylalanine in two simple steps with 90% overall yield.

  开发了一种由苯丙氨酸衍生的手性酰胺，它作为有效的有机催化剂，用于烯丙基三氯硅烷与芳基、杂芳基和α,β-不饱和醛的反应，以良好的产率（高达90%）和高对映选择性（高达99%）得到所需的同烯丙基醇。实验结果和DFT计算表明，与邻/间位取代的芳香醛相比，对位取代的芳香醛作为底物在产物中显示出更高的对映体过量值。1H和13C NMR光谱学研究证实了计算结果。手性有机催化剂可以通过两个简单步骤从光学纯苯丙氨酸轻松合成，总产率为90%。

  A new class of amine N-oxides derived from trans-2,5-diphenylpyrrolidine were synthesized in enantiomerically pure form and tested as metal-free catalysts in the reaction of aldehydes with allyl(trichloro)silane to afford homoallylic alcohols. The products were obtained in fair to good yields and up to 85% ee. The behavior of structurally different catalysts and the influence of a coordinating unit present in the organocatalyst on controlling the stereochemical efficiency of the reaction were also investigated. Noteworthy a catalyst capable of promoting the allylation of aliphatic aldehydes with an almost unprecedent and unusually high enantioselectivity, up to 85%, was identified.

  A series of enantiomerically pure mono- and bis-aryl tert-butyl sulfoxides were synthesised to promote the enantioselective allylation of aldehydes with allyltrichlorosilane. Moderate to good yields and modest to high enantioselectivities were achieved. The absence of nonlinear effect, spacer effect, promoter loading and concentration effect indicate that only one molecule of aryl tert-butyl sulfoxide is involved in the stereodetermining step.
