  Regio- and stereoselective preparation of ascomycin-d1 and FK 506-d1

  摘要：

  免疫抑制大环内酯药物阿斯科霉素1和FK 506 2在C(32)处采用Curran的自由基转位方法进行立体选择性氘代化。测试了AIBN和Et3B/O2作为自由基引发剂，用Bu3SnD作为还原剂进行自由基转位/还原步骤。尽管仅有细微结构差异，阿斯科霉素和FK 506在自由基转位/还原条件下表现出显著不同的行为。使用Et3B/O2作为引发剂时观察到更高的立体选择性，推测是由于在这种情况下反应温度较低。© 2002 John Wiley & Sons, Ltd.

  Storable Arylpalladium(II) Reagents for Alkene Labeling in Aqueous Media

  摘要：

  We show that arylpalladium(II) reagents linked to biotin and indocyanine dye residues can be prepared by decarboxylative palladation of appropriately substituted electron-rich benzoic acid derivatives. When prepared under the conditions described, these organometallic intermediates are tolerant of air and water, can be stored for several months in solution in dimethyl sulfoxide, and permit biotin- and indocyanine dye-labeling of functionally complex olefinic substrates in water by Heck-type coupling reactions.

• Rapid synthesis of 11C-labeled FK506 for positron emission tomography

  The present study describes a rapid synthesis method for labeled [C-11]FK506 for positron emission tomography (PET). A one-pot reaction from [C-11]CH3I, involving a Wittig reaction as the key carbon-carbon bond formation was developed. The chemical process was accomplished using a designed, fully automated synthetic apparatus, and an injectable solution of [C-11]FK506 was obtained in only 34 min from [C-11]CH3I. The decay-corrected radiochemical yield based on [C-11]CH3I was 11.9%, and the specific activity was 39.8 GBq/mumol. (C) 2003 Elsevier Science Ltd. All rights reserved.
• Synthesis of derivatives of FK 506 and FR 900520: modifications at the binding domain
  作者：Gerhard Emmer、Sabine Weber-Roth

  日期：1992.7

  The synthesis of 9-deoxo-FK 506 (13a), 9-deoxo-FR 900520 (13b), 9-deoxo-10(R)-deoxy-FR 900520 (14) and its 10(S) isomer 15 is described. Radical deoxygenation/elemination of the 9-di-hydro-9,10-thiocarbonates 5a,5b,6a and 6b gave the 9,10 unsaturated compounds 7a (7b) or 8a (8b) which were further transferred by hydration or hydrogenation. Different E/Z ratios of 7a (7b) were obtainted when nBu3SnH or [(CH3)3Si]3SiH in combination with AIBN or Et3B were used, allowing the selective preparation of both isomers. Two possible reaction mechanisms are discussed.
