    Total Synthesis of Natural and Unnatural Lamellarins with Saturated and Unsaturated D-Rings
    摘要:
    Twenty-eight natural and unnatural lamellarins with either a saturated or an unsaturated D-ring were synthesized according to our developed synthetic route. The key step involved the Michael addition/ring closure (Mi-RC) of the benzyldihydroisoquinoline and alpha-nitrocinnamate derivatives, which provided the 2-carboethoxypyrrole intermediates in moderate to good yields (up to 78% yield). Subsequent hydrogenolysis/lactonization furnished lamellarins with a saturated D-ring in excellent yields (up to 93% yield). DDQ oxidation of the saturated lamellarin acetates led directly to the corresponding unsaturated analogues in 54-95% yield. In addition, only two steps in our developed strategy require column chromatography.

  • Syntheses of Lamellarins I and K by [3 + 2] Cycloaddition of a Nitrone to an Alkyne
    作者:Maite Díaz、Enrique Guitián、Luis Castedo
    DOI:10.1055/s-2001-15143
    日期:——
    Lamellarins I and K were obtained by a new approach based on the 1,3-dipolar cycloaddition of a nitrone to an alkyne. The key cycloaddition yields an isoxazoline which rearranges to afford the central pyrrole ring.

  • Synthesis of (±)-Glaucine and (±)-Neospirodienonevia an One-PotBischlerNapieralski Reaction and Oxidative Coupling by a Hypervalent Iodine Reagent
    作者:Wei-Jan Huang、Om V. Singh、Chung-Hsiung Chen、Shoei-Sheng Lee

    日期:2004.1
    acids, i.e., 4a–e, via a practical and efficient one-pot Bischler–Napieralski reaction, followed by NaBH4 reduction, produced a series of 1-benzyl-1,2,3,4-tetrahydroisoquinolines, i.e., 5a–e, in satisfactory yields (Scheme 3). Oxidative coupling of the N-acyl and N-methyl derivatives 6a–e of the latter with hypervalent iodine ([IPh(CF3COO)2]) yielded products with two different skeletons (Scheme 4). The
    3,4- dimethoxybenzeneethanamine(缩合3D)和各种酸苯乙酸,即,图4a - ë,经由一个实用,高效的一锅煮施勒-纳皮耶拉尔斯基反应,随后加入NaBH 4还原,产生了一系列的1-苄基1, 2,3,4-四氢异喹啉,即,图5a - ê,在令人满意的产率(方案3)。后者的N-酰基和N-甲基衍生物6a – e与高价([IPh(CF 3 COO)2 ])产生具有两个不同骨架的产物(方案4)。N-酰基衍生物6a - c的主要产物为(±)-N-酰基亚螺二酮2a - c,次要产物为3,4-二氢异喹啉7。然而,(±)-甘酸(1)是从N-甲基衍生物6e开始的主要产物。提出了用于形成这两种类型骨架的可能的反应机理(方案5)。
