  • A novel synthetic method of dihydro-4-pyrone derivatives and its application to the syntheses of ar-atlantone and (±)-ar-turmerone
    作者:Takashi Sakai、Kazuyoshi Miyata、Mutsumi Ishikawa、Akira Takeda
    DOI:10.1016/s0040-4039(00)94935-9
    日期:1985.1
    Reaction of 1,3-dihalo-3-methy]-2-butanone with t-butyl acetoacetate (NaH) gave t-butyl 3,4-dihydro-2,2,6-trimethyl-4-oxo-2H-pyran-5-carboxylate via the Favorskii-type rearrangement. Michael addition of 4-methylphenyllithium (CuI) followed by ring cleavage with Me3 SiCl-NaI in DMF or PrCN afforded ar-atlantone as well as (±)-ar-turmerone selectively.

    A convergent approach to the forskolin skeleton is described. Assembly of a simplified tricyclic framework is achieved in a single step via the dihydropyrone Diels–Alder reaction. Selective manipulation of the resulting cycloadduct, in conjunction with an unusual equilibration of the C8 stereocenter, provides access to scaffolds that differ in relative stereochemistry at both the A/B and B/C ring junctions
    描述了毛喉素骨架的收敛方法。通过二氢吡喃酮狄尔斯-阿尔德反应一步即可组装出简化的三环骨架。对所得环加合物的选择性操作,结合 C8 立体中心的异常平衡,提供了在 A/B 和 B/C 环连接处相对立体化学不同的支架。

  • On the Stereochemistry of the Dihydropyrone Diels−Alder Reaction
    作者:Punit P. Seth、Nancy I. Totah
    DOI:10.1021/ol9909637
    日期:1999.11.1
    [GRAPHICS]The Diels-Alder reaction of activated dihydropyrones with electron-rich dienes proceeds with synthetically useful levels of diastereoselectivity Product ratios vary with the nature and location of substituents on diene and dienophile, as well as with reaction conditions. Lewis acid catalyzed reactions of related pyrone and benzopyrone dienophiles are also diastereoselective.
