  Phase-Transfer Catalysed Enantioselective Epoxidation of Estra-Δ5(10),9(11)-diene Using Chiral Ammonium Salts Derived from Cinchona Alkaloids

  摘要：

  A modified phase-transfer catalysed enantioselective epoxidation of estra-Delta(5(10),9(11))-diene, an important intermediate of anti-early pregnancy drug mifepristone 1, have been determined and investigated. Eight chiral ammonium salts (PTC A-H), used as phase-transfer catalysts, have been synthesized from cinchona alkaloids. Among them, PTC G and PTC H have exhibited satisfying catalytic activity to improve the ratio of alpha/beta epoxide up to 7:1.

  Preparation of Enantiopure 1-Azabicyclo[3.2.2]nonanes Functionalized at Carbon C3, from Cinchonine and Cinchonidine. Stereoselective Solvolysis and an Easily Enolizable Ketone

  摘要：

  Solvolysis of C9 mesylated cinchonidine 1-OMs and cinchonine 2-OMs in solvent MeOH, EtOH, and CF3CH2OH affords ring-expanded 1-azabicyclo[3.2.2]nonanes oxygenated at carbon C3 ("second Cinchona rearrangement"). The newly introduced substituents at C3 and the neighboring quinolyl group Q' at C2 adopt quasiequatorial positions. The derived 1-azabicyclo[3.2.2]nonan-3-ones 5 and 6 are easily equilibrated. On contact with MeOD uptake of deuterium takes place at room temperature.

• The First and Second <i>Cinchona</i> Rearrangement. Two Fundamental Transformations of Alkaloid Chemistry

  Stereochemistry, products, and driving forces of the “first and second Cinchona rearrangement” have been investigated and a unified theory is presented. The first cage expansion affords [3.2.2]azabicyclic α-amino ether and is formulated via a configurationally stable bridgehead iminium ion and quasiequatorial nucleophilic attack. The second cage expansion affords β-functionalized [3.2.2]azabicycles

  研究了“第一和第二次金鸡纳重排”的立体化学，产物和驱动力，并提出了统一的理论。第一次笼扩展提供了[3.2.2]氮杂双环α-氨基醚，并通过构型稳定的桥头亚胺离子和准四亲核攻击进行配制。第二个笼扩展提供了β-官能化的[3.2.2]氮杂双环。在这种情况下，假定存在非经典的氮桥阳离子，以说明保持构型和保持架扩展的潜在可逆性。第二种重新排列因所谓的肚带而受到青睐在三氟乙醇中的碱（6'-R = H）。在所有情况下，立体电子因素，C9处的电子需求，基态构型和溶剂类型都是至关重要的。描述了从9- nat前体制备9-表位构型的金鸡纳生物碱的两步方案。

  [reaction: see text] Intramolecular 1,3-dipolar cycloadditions of cinchona azides to the C10-C11 alkyne and C10-C11 olefin unit of the alkaloid have been designed via tandem strategy. A variety of fused triazoles and triazolines with a bis-azahomotwistane skeleton have been prepared. In trifluoroethanol, O-mesylcinchonidine 7-OMs and NaN(3) furnish triazole 8 as well as cage-expanded 1,5-diazatricyclo[4
