  • Chiral Chromium(III) Porphyrins as Highly Enantioselective Catalysts for Hetero-Diels–Alder Reactions Between Aldehydes and Dienes
    作者:Albrecht Berkessel、Erkan Ertürk、Cécile Laporte

    日期:2006.1
    tetrafluoroborate. These hitherto unknown chiral chromium porphyrins are efficient and highly enantioselective catalysts for the hetero-Diels–Alder reaction of aliphatic, aromatic, and heteroaromatic aldehydes with dienes of varying electron density. In the case of 1-methoxy-3-(trimethylsilyloxy)butadiene (“Danishefsky's diene”), enantiomeric excesses >90% were achieved in a number of cases, with furfural

    DOI:10.1246/cl.2008.632
    日期:2008.6.5
    Various heterogeneously or homogeneously hybridized salen/salan ligands were synthesized, and study of hetero Diels–Alder reactions using their chromium complexes as catalysts revealed that a well-designed heterogeneously hybridized ligand serves as a chiral auxiliary as efficiently as the homogeneously hybridized ligand and its chromium complex has high catalytic activity.

    applied to the hetero-Diels–Alder reaction of Danishefsky’s diene with various aldehydes. The reactions afford the corresponding 2-substituted 2,3-dihydro-4H-pyran-4-ones in high yields and enantioselectivities (up to 96 % ee). The effect of different counteranions of the complex on reactivity as well as enantioselectivity has been investigated. Besides Danishefsky’s diene, reaction of the less reactive
    合成了一种以DIANANE(endo,endo-2,5-diaminonorbornane)为手性骨架的新型铬-salen配合物,并将其应用于Danishefsky's二烯与各种醛的杂Diels-Alder反应。该反应以高产率和对映选择性(高达 96% ee)得到相应的 2-取代的 2,3-二氢-4H-吡喃-4-酮。已经研究了配合物的不同抗衡阴离子对反应性和对映选择性的影响。除了Danishefsky的二烯之外,反应性较低的1-甲氧基丁二烯与苯甲醛和乙醛酸乙酯的反应也可以通过铬催化剂进行。(© Wiley-VCH Verlag GmbH & Co.

    Methods of performing cycloadditions are described that include (a) combining a first reactant and a second reactant in a hydrogen bonding solvent to form a reaction mixture; and (b) reacting the first reactant and the second reactant to form a cycloadduct. Methods of performing asymmetric catalytic reactions are also described that include (a) combining a first reactant, a second reactant, and a catalytic amount of a chiral hydrogen-bond donor in a solvent to form a reaction mixture; and (b) reacting the first reactant and the second reactant to form an enantiomeric excess of a reaction product. Reaction mixtures corresponding to these methods are also described.

    than 95% of the Salen incorporated being actually accessible for complexation (by elemental analysis). The polymer-bound Mn and Cr complexes were used as catalysts for epoxidations of six phenyl-substituted olefins (m-CPBA/NMO; products 22a-f), and for dihydropyranone formation from the Danishefsky diene and aldehydes (PhCHO, C5H11CHO, C6H11CHO, products 23a-c). There are several remarkable features
