An efficient Na2S2O8-promoted radical cyclization reaction of acrylamides with the tertiary cycloalkanols has been developed. This one pot procedure involves a tandem C–C bond cleavage and two C–C bonds formation process. The key advantages of this protocol are its transition-metal free, its operational simplicity and its excellent functional group tolerance, thus allowing a facile access to oxindoles
已经开发了有效的Na 2 S 2 O 8促进的丙烯酰胺与叔环烷醇的自由基环化反应。此一锅法涉及串联的C–C键断裂和两个C–C键形成过程。该协议的主要优点是无过渡金属,操作简单和出色的官能团耐受性,因此可以轻松获得含羰基的羟吲哚。
Lewis-Acid-Catalyzed Tandem Cyclization by Ring Expansion of Tertiary Cycloalkanols with Propargyl Alcohols
A new method for the efficient synthesis of hexahydro-1H-fluorene and octahydrobenzo[a]azulene derivatives through a ring-expansion strategy is reported. With an appropriate combination of thulium(III) trifluoromethanesulfonate and 13X molecular sieves, a range of unsaturated polycycliccompounds were obtained in good yields. Mechanism studies reveal that the reaction is more likely to undergo Meyer–Schuster
We report the first terminal trifluoromethylation at aryl and alkyl ketones’ γ, δ, ε, or more remote sites via the selective C–C bond cleavage of cycloalkanols. The noncovalent interactions between alcohols and hypervalent iodines(III) reagents were disclosed to activate both alcohols and the Togni I reagent in the dual photoredox/copper catalysis for the transformation. This reaction was scalable
我们报告了通过环烷醇的选择性 C-C 键断裂在芳基和烷基酮的 γ、δ、ε 或更远的位点发生的第一个末端三氟甲基化。公开了醇和高价碘 (III) 试剂之间的非共价相互作用,以在双光氧化还原/铜催化转化中激活醇和 Togni I 试剂。该反应可扩展到克级合成,适用于结构复杂的类固醇三氟甲基化,并可扩展到五氟乙基化。
