    inevitably are achiral in the original salen structures. 8 Tests in sulfide oxidations with cumyl hydroperoxide as oxidant and the oxovanadium(IV) complex of ( S,S)-1 as catalyst proved successful, giving sulfoxides in high yields, although as racemates. We now synthesized related bis(sulfoximine) ( S,S-2 and were pleased to note that its copper complex showed both high activity and enantioselectivity

    In presence of bismuth (III) chloride, a carbonylated electrophile (ethyl mesoxalate or glyoxylate) and usual diene led selectively (65 to 100%) the hetero carbonyl-Diels-Alder reaction with the ene reaction product. BiCl3 exhibits strong catalytic activity and, compared with previous literature, reacts under mild conditions.

    A group of chiral [(salen)Cr(III)] + BF 4 - complexes, with enhanced steric hindrance in 3,3'-positions of salicylidene moiety, has been synthesized and applied for the oxo-Diels-Alder reaction of alkyl glyoxylates with cyclohexa-1,3-diene. A readily accessible complex that bears bulky adamanthyl substituents revealed its potential, leading to the cycloadducts with excellent selectivity (up to endolexo

  • Zinc(II)-catalysed asymmetric hetero-Diels–Alder reactions of conjugated dienes with glyoxylate
    作者:Sulan Yao、Mogens Johannsen、Karl Anker Jørgensen
    DOI:10.1039/a701882g
    日期:——
    The zinc(II)-catalysed hetero-Diels–Alder reaction of the conjugated dienes 2,3-dimethylbuta-1,3-diene and cyclohexa-1,3-diene with ethyl glyoxylate has been studied in the presence of different C2-symmetric bisoxazolines. The zinc(II)-catalysed reaction of 2,3-dimethylbuta-1,3-diene with ethyl glyoxylate gives both the hetero-Diels–Alder and ene products, the former being the major product with an enantiomeric excess up to 87%. The hetero-Diels–Alder∶ene ratio is relatively independent of the catalytic system and the solvent and is in the range 1∶0.5–1∶0.8. For the zinc(II)-catalysed reaction of cyclohexa-1,3-diene with ethyl glyoxylate, the hetero-Diels–Alder product is formed in up to 84% isolated yield and with an enantiomeric excess up to 65%. The enantiomeric excess for this reaction is very dependent on the solvent, with MeNO2 generally lowering the enantiomeric excess compared with CH2Cl2. Based on the absolute stereochemistry of the hetero-Diels–Alder products and semi-empirical calculations on different bisoxazoline–zinc(II)–ethyl glyoxylate intermediates the mechanism for the reaction is discussed.
    在不同的 C2 对称双噁唑啉存在下,研究了锌(II)催化的共轭二烯 2,3-二甲基丁-1,3-二烯和环己-1,3-二烯与乙醛酸乙酯的杂 DielsâAlder 反应。 锌(II)催化的 2,3-二甲基丁-1,3-二烯与乙醛酸乙酯的反应产生了杂-DielsâAlder 和烯产物,前者是主要产物,对映体过量率高达 87%。杂-DielsâAlderâceene 的比例与催化体系和溶剂相对无关,范围在 1â¶0.5â1â¶0.8。锌(II)催化的环己-1,3-二烯与乙醛酸乙酯的反应中,杂-DielsâAlder 生成物的分离收率高达 84%,对映体过量率高达 65%。该反应的对映体过量与溶剂有很大关系,与 CH2Cl2 相比,MeNO2 通常会降低对映体过量。根据杂-DielsâAlder 产物的绝对立体化学性质以及对不同双噁唑啉锌(II)-乙醛酸乙酯中间体的半经验计算,讨论了该反应的机理。
