  Sequential Baylis–Hillman reaction and radical cyclization of furanose derivatives: expeditious approach to enantiopure benzo-fused nine-membered oxacycles

  摘要：

  A regioselective 9-endo-trig aryl radical cyclization of D-glucose derived diastereomeric Baylis-Hillman reaction products with Bu3SnH led to highly functionalized tricyclic benzannulated ethers incorporating cis- and trans-9,5 bicyclic systems in good yields. Degradation of one of the products afforded an enantiopure multifunctionalized benzoxonine derivative. (c) 2006 Elsevier Ltd. All rights reserved.

  分子内无碱Sonogashira反应用于合成嵌入碳水化合物模板中的苯环化手性大环化合物

  摘要：

  建立了基于无碱分子内Sonogashira反应的通用方法，用于融合双向和三环系统的多样性导向合成（DOS），该系统包含嵌入碳水化合物模板中的苯并环化的10至13元手性大环化合物。通过预先设计手性结构单元，可以制备出具有不同环尺寸的大环。碱敏感基团（例如乙酰基和TBDPS）在反应条件下仍然存在。

  Palladium-catalyzed intramolecular aryl etherification using bulky binaphthylphosphane or bis(diphenylphosphanyl)ferrocene ligands is shown to be a convenient method for the synthesis of eight-membered oxygen heterocycles. Application of this methodology to a sugar derivative led to the synthesis of chiral benzodioxocine. (© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2008)

  established for the diversity‐oriented synthesis (DOS) of fused bi‐ and tricyclic systems containing benzannulated, 10‐ to 13‐membered chiral macrocycles embedded in carbohydrate templates. Macrocycles with different ring sizes have been prepared by pre‐designing the chiral building blocks. Base‐sensitive groups like acetyl and TBDPS survived the reaction conditions.
