  • Total Synthesis with a Chirogenic Opening Move Demonstrated on Steroids with Estrane or 18a-Homoestrane Skeleton
    作者:Gerhard Quinkert、Michael Del Grosso、Astrid Döring、Wolfgang Döring、Ralf I. Schenkel、Markus Bauch、Gernot T. Dambacher、Jan W. Bats、Gottfried Zimmermann、Gerd Dürner
    DOI:10.1002/hlca.19950780524
    日期:1995.8.9
    A concept of first choice for the synthesis of the title compounds had been proposed by Dane in the late 1930s. It was soon turned down, because the opening move–a chirogenic Diels-Alder reaction – did not work. With Lewis acids as mediators, however, a successful start has been achieved now. With Ti complexes of chelating ligands (Seebach's TADDOLs (= α,α,α′,α′-tetraaryl-1,3-dioxolane-4,5-dimethanols))
    Dane在1930年代后期提出了合成标题化合物的首选方法。很快就被拒绝了,因为开场动作–致色Diels - Alder反应–无效。但是,以路易斯酸为介质,现在已经取得了成功的开始。使用螯合配体的Ti络合物(Seebach 's TADDOLs(=α,α,α',α'-四芳基-1,3-二氧戊环-4,5-二甲醇)),确实发生了所需加合物的对映选择性形成。已经完成了2和3a的有效总合成。
  • Catalysis of a Diels−Alder Reaction by Amidinium Ions
    作者:Tilmann Schuster、Markus Kurz、Michael W. Göbel
    DOI:10.1021/jo991372x
    日期:2000.3.1
    lipophilic amidinium ions catalyze a cycloaddition reaction representing the key step of the Quinkert-Dane estrone synthesis. Hydrogen-bond-mediated association with the organic cation leads to an electrophilic activation of the dienophile and to enhanced rates of the Diels-Alder reaction. The observed effects are similar to those expected from mild Lewis acids. In competition experiments, amidinium catalysis
    molecular和胍是分子识别和客体化学中重要的官能团。此处显示亲脂性am离子可催化环加成反应,该反应代表了Quinkert-Dane雌酮合成的关键步骤。氢键介导的与有机阳离子的缔合导致亲二烯体的亲电子活化并提高了狄尔斯-阿尔德反应的速率。观察到的效果与温和的路易斯酸所预期的效果相似。在竞争实验中,idi催化促进了电子缺乏程度较低的亲双烯体的反应。
  • E. Dane's route to estrone revisited
    作者:Gerhard Quinkert、Michael del Grosso、Astrid Bucher、Jan W. Bats、Gerd Dürner
    DOI:10.1016/s0040-4039(00)92705-9
    日期:1991.7
    The chirogenic Diels/Alder reactions of the general pattern AB + D --> ABCD, (i): 2 + 3 --> rac-8a (major) + rac-9a (minor) (85%), (ii): 2 + 10a --> rac-11a (89%), and (iii): 2 + 10b --> rac-11b (90%), now have been accomplished in the presence of Lewis acid, (i): BF3.OEt2, (ii) or (iii): TiCl4. Case (iii) may be used as the initial move towards (+/-)-norgestrel (rac-14).
  • Axially Chiral Amidinium Ions as Inducers of Enantioselectivity in Diels−Alder Reactions
    作者:Tilmann Schuster、Markus Bauch、Gerd Dürner、Michael W. Göbel
    DOI:10.1021/ol991276i
    日期:2000.1.1
    Enantioselective catalysis of Diels-Alder reactions is mostly achieved by coordinating the dienophile to relatively strong chiral Lewis acids. Here we report on a novel approach employing the hydrogen bond mediated association of dienophiles to chiral host molecules, In a reaction forming the steroid skeleton of norgestrel, chiral amidinium ions induce 5:ent-5 ratios of up to 2,5:1. Improved and simplified amidinium catalysts may become interesting candidates to perform stereoselective transformations.
  • Enantioselective Synthesis of (+)-Estrone Exploiting a Hydrogen Bond-Promoted Diels−Alder Reaction
    作者:Marko Weimar、Gerd Dürner、Jan W. Bats、Michael W. Göbel
    DOI:10.1021/jo100053j
    日期:2010.4.16
    Starting from Dane’s diene and methylcyclopentenedione, (+)-estrone is synthesized along the Quinkert−Dane route in 24% total yield. The key step is an enantioselective Diels−Alder reaction promoted by an amidinium catalyst as efficiently as by a traditional Ti-TADDOLate Lewis acid.
    从 Dane 的二烯和甲基环戊烯二酮开始,沿 Quinkert-Dane 路线合成 (+)-雌酮,总产率为 24%。关键步骤是由脒催化剂与传统的 Ti-TADDOLate Lewis 酸一样有效地促进对映选择性 Diels-Alder 反应。
