important scaffolds, including tetralins, chromanes, and indanes, can be easily prepared by this protocol. Finally, the synthetic application of this methodology is demonstrated by the concise totalsynthesis of (±)-russujaponol F in a four-step sequence starting from readily available phenylacetic acid and pivalic acid through sequential functionalizations of four C-H bonds.
实际的 CH/CH 偶联反应的开发仍然是一项具有挑战性但具有吸引力的合成冒险,因为它避免了对两个偶联伙伴进行预功能化以生成 CC 键的需要。在此,我们报告了由基于环戊烷的单-N-保护的 β-氨基酸配体实现的游离脂肪酸的环化 C(sp3)-H/C(sp2)-H 偶联反应。该反应使用廉价的过碳酸钠 (Na2CO3·1.5H2O2) 作为唯一的氧化剂,并生成水作为唯一的副产物。该协议可以很容易地制备一系列生物学上重要的支架,包括四氢萘、色烷和茚满。最后,
