  Reactions of vinylidenecyclopropanes with xanthydrol and xanthene

  摘要：

  Vinylidenecyclopropanes undergo ring-opening reactions with xanthydrol in the presence of BF(3)center dot OEt(2) or with xanthene in the presence of DDQ at 0 degrees C in 1,2-dichloroethane to give the corresponding conjugate triene derivatives in moderate to good yields. Plausible reaction mechanisms have been discussed on the basis of previous literature and the control experiments. The further transformation of these trienes has been disclosed in DCE in the presence of BF(3)center dot OEt(2) along with a plausible reaction mechanism. (C) 2010 Elsevier Ltd. All rights reserved.

  Brønsted Acid TfOH-Mediated [3 + 2] Cycloaddition Reactions of Diarylvinylidenecyclopropanes with Nitriles

  摘要：

  Diarylvinylidenecyclopropanes undergo a [3 + 2] cycloaddition reaction with MeCN in the presence of Bronsted acid TfOH to give the corresponding 3,4-dihydro-2H-pyn-ole derivatives 2 in moderate to excellent yields under reflux within a short time. As for the diarylvinylidenecyclopropane substrate containing a strongly electron-donating methoxy group on the benzene ring, the reaction leads to the formation of a different type of 3,4-dihydro-2H-pyrrole derivatives 4 under the same conditions.

  We report in this paper a Lewis acid [Nd(OTf)(3)]-catalyzed protocol to construct compounds containing a 5-7-6 tricyclic framework in good yield from readily accessible starting materials vinylidenecyclopropanes (VDCPs) 1 and enynols 2a-c under mild conditions. Upon examination of the scope and limitations of this reaction, it was found that the corresponding highly functionalized cyclopentane derivatives

  日期：2009.8

  The reaction of vinylidenecyclopropanes 1 with diphenylphosphinodithioic acid produces the adducts 3 in good to high yields in toluene upon heating at 100 °C within 1 h, whereas adducts 5 are obtained in excellent yields in reversed regioselectivity from the reaction of 1 with thioacetic acid under identical conditions. The radical reaction processes have been discussed on the basis of deuterium labeling

  亚乙烯基环丙烷1与二苯基次膦二硫代酸的反应在100°C下加热1小时后，在甲苯中生成高至高收率的加合物3，而在相同条件下1与硫代乙酸的反应则以极高的收率获得了高收率的加合物5。情况。在氘标记实验和在自由基抑制剂（TEMPO和BHT）或质子清除剂（DTBMP）存在下的对照实验的基础上，对自由基反应过程进行了讨论。

  Manganese(III)-mediated oxidative annulation of vinylidenecyclopropanes with 1,3-dicarbonyl compounds in acetonitrile/acetic acid produces the corresponding functionalized dihydrofuran derivatives in moderate to good yields under mild conditions. The substrate scope has been examined and a plausible reaction mechanism has been also proposed on the basis of experimental results and previous literature
