  Rhodium(I)-Catalyzed Intramolecular Ene Reaction of Vinylidenecyclopropanes and Alkenes for the Formation of Bicyclo[5.1.0]octylenes

  摘要：

  An efficient catalytic system for the intramolecular ene reaction of allene and alkene of diarylvinylidenecyclopropanes has been established. The reaction was achieved by using [RhCl(CO)(2)](2) as the catalyst In co-solvents of toluene and acetonitrile. MeCN was found to play a crucial role in controlling the reaction toward formation of bicyclo[5.1.0]octylene derivatives. An alternative system consisting of [RhCl(CO)(2)](2) and toluene in the absence of MeCN was found to give [2 + 2] cycloaddition adducts. The structures have been unambiguously determined by X-ray structural analysis. Deuterium labeling experiments were conducted to confirm the mechanism hypothesis.

  A novel synthetic protocol that uses halogenation reagents (NBS, NIS and selectfluor) to initiate intramolecular ring-opening reactions of diarylvinylidenecyclopropanes (VDCPs) connected to alcohol-bearing chains has been developed. The approach provides a variety of halogenated tetrahydropyran derivatives in moderate to good yields under mild conditions. Plausible reaction mechanisms are proposed on the basis of previous literature and the substrate scope has been carefully examined.

  An intramolecular ring-opening of vinylidenecyclopropanes (VDCPs) tethered with alcohol chains has been established. A series of transition metal catalysts and their combinations have been screened under mild conditions, and a cocatalyst system consisting of [(Ph3PAu)(3)O]BF4 (4 mol %) and AgOTf (4 mol %) was found to catalyze the reaction to completion within 10-30 min in 1,4-dioxane at 60 degrees C to give allene-functionalized tetrahydropyrans.

  vinylidenecyclopropanes with diphenyl diselenide in the presence of AIBN and upon heating gives the corresponding bicyclo[3.1.0]hexane derivatives in good yields. These compounds undergo thermal‐induced radical 1,4‐hydrogen shifts through a ring‐opening pathway of allylic cyclopropane to give the corresponding cyclohexene derivatives stereoselectively in good yields at 200 °C (see scheme).

  自由基变换器：在AIBN存在下并加热后，将亚乙烯基环丙烷与二苯二硒化物化学转化，得到高收率的相应双环[3.1.0]己烷衍生物。这些化合物通过烯丙基环丙烷的开环途径经历热诱导的自由基1,4-氢转移，从而在200°C下以良好的产率立体选择性地生成相应的环己烯衍生物（参见方案）。
