    Total synthesis of bidensyneosides A2 and C: remarkable protecting group effects in glycosylation
    摘要:
    Bidensyneosides are a group of five recently identified polyacetylenic glucosides from Bidens parviflora WILLD, a traditional Chinese medicinal plant that contains rich bioactive natural products. It was shown that bidensyneosides inhibited both histamine release and nitric oxide production. The synthesis of bidensyneoside A2 (2) and C (4) as well as 3-deoxybidensyneoside C (5) are described. These syntheses establish a synthetic entry to the bidensyneosides and confirm the stereochemistry at C3. Furthermore, a remarkable protecting Group effect on orthoester formation was observed during the glycosylation reaction. (C) 2004 Elsevier Ltd. All rights reserved.

  • First Total Synthesis of Naturally Occurring (−)-Nitidon and Its Enantiomer
    作者:Fabio Bellina、Adriano Carpita、Luca Mannocci、Renzo Rossi
    DOI:10.1002/ejoc.200400101
    日期:2004.6
    The first total synthesis of naturally occurring (−)-nitidon and its enantiomer is reported. The best of the routes investigated for preparation of these enantiomerically pure compounds involves a modification of the Cadiot−Chodkiewicz reaction and the Sharpless asymmetric epoxidation of an (E)-2-ene-4,6-diyn-1-ol as key steps and proceeds in five steps and 18% overall yield. Both enantiomers of nitidon

  • Stereoselective Total Syntheses of Polyacetylene Plant Metabolites via Ester-Tethered Ring Closing Metathesis
    作者:Bernd Schmidt、Stephan Audörsch
    DOI:10.1021/acs.joc.6b02987
    日期:2017.2.3
    Total syntheses of five naturally occurring polyacetylenes from three different plants are described. These natural products have in common an E,Z-configured conjugated diene linked to a di- or triyne chain. As the key method to stereoselectively establish the E,Z-diene part, an ester-tethered ring-closing metathesis/base-induced eliminative ring opening sequence was used. The results presented herein
    描述了来自三种不同植物的五种天然存在的聚乙炔的总合成。这些天然产物共同具有连接至二或三炔链的E,Z-构型的共轭二烯。作为立体选择性地建立E,Z-二烯部分的关键方法,使用了酯束缚的开环复分解/碱基诱导的消除开环序列。本文介绍的结果不仅展示了这种束缚的RCM变体的实用性,而且还提示我们建议应修改或至少重新考虑最初分配自白术的手性聚乙炔的绝对构型。
