  Enantioselective Friedel–Crafts alkylations catalysed by well-defined iridium and rhodium half-sandwich complexes

  摘要：

  Aqua-complexes (S-M,R-C)-[C-p*M((R)-prophos)(H2O)][SbF6](2)(M = Rh 1, Ir 2) catalysed the alkylation of alpha,beta-unsaturated aldehydes with aromatics and heteroaromatics but in some cases, mixtures of products were obtained. Complexes 1 and 2 were also used to activate nitroalkenes for the Friedel-Crafts alkylation of a variety of aromatics and heteroaromatics, in particular, 1,3,5-trimethoxybenzene. For this substrate, the monoalkylated adduct was obtained in quantitative yield with enantioselectivities of up to 73% ee being achieved. The intermediate catalyst/nitroalkene was isolated and characterized and the complex catalyst/adduct was detected spectroscopically. From these data a plausible catalytic cycle is proposed.

  Nonmetallic, chiral organic catalysts are used to catalyze the 1,4-addition of an aromatic nucleophile to an &agr;,&bgr;-unsaturated aldehyde. The aromatic nucleophile may be an N,N-disubstituted aniline compound, or an analog thereof. The reaction is efficient and enantioselective, and proceeds with a variety of substituted and unsubstituted aromatic nucleophiles and aldehydes. The invention also provides a method for the deamination of aromatic N,N-disubstituted amines such as those resulting from the 1,4-addition of an aromatic nucleophile to an &agr;,&bgr;-unsaturated aldehyde.

  非金属手性有机催化剂被用于催化芳香核亲电体对α,β-不饱和醛的1,4-加成反应。芳香核亲电体可以是N,N-二取代苯胺化合物，或其类似物。该反应高效、选择性，可用于各种取代和未取代的芳香核亲电体和醛。该发明还提供了一种去氨化芳香N,N-二取代胺类化合物的方法，例如由芳香核亲电体对α,β-不饱和醛的1,4-加成反应产生的化合物。
