  powerful synthetic strategies for making new substances that have been of significant importance in chemistry, medicine, and material fields. Conventional tactics employ various preformed allylation and propargylation reagents. In this study, a conceptually novel copper-catalyzed and B2pin2-mediated Umpolung reactivity of propargylic carbonates has been achieved for the first time, realizing both allylation

  烯丙基化和炔丙基化是制造新物质的两种强大的合成策略，在化学、医学和材料领域具有重要意义。常规策略采用各种预先形成的烯丙基化和炔丙基化试剂。在这项研究中，首次实现了概念上新颖的铜催化和B 2 pin 2介导的炔丙基碳酸酯的Umpolung反应，无需额外的还原剂即可实现醛和酮的烯丙基化和炔丙基化。高效生成了三种烯丙基化产物和一种炔丙基化产物，且所有烯丙基化产物均以顺式构型为主。配体的选择在调节 Umpolung 模式中起着至关重要的作用。合成应用已在包括天然产物合成在内的无数进一步转化中得到证实，并且已进行系统的机理研究以揭示对 Umpolung 过程的详细见解。
• Total synthesis of bidensyneosides A2 and C: remarkable protecting group effects in glycosylation

  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.
