  • An Efficient Approach to Functionalized Benzo[<i>a</i>]xanthones through Reactions of 2-Methyl-3-(1-alkynyl)chromones with Electron-Deficient Chromone-Fused Dienes
    作者:Jian Gong、Fuchun Xie、Hong Chen、Youhong Hu
    DOI:10.1021/ol101496w
    日期:2010.9.3
    An efficient tandem process was developed to synthesize diversified benzo[a]xanthones from 2-methyl-3-(1-alkynyl)chromones with electron-deficient chromone-fused dienes. This unusual reaction, involving multiple steps and not requiring the use of transition metal catalysts or an inert atmosphere, results in the formation of three new C−C bonds and one C−O bond.

  • Efficient Construction of a 3<i>C</i>-Xanthone-Linked 3<i>C</i>-Chromone Scaffold by Novel Double Michael Additions and Cyclizations
    作者:Fuchun Xie、Hong Chen、Youhong Hu
    DOI:10.1021/ol101100d
    日期:2010.7.2
    A novel base-promoted cascade reaction of 2-methyl-3-(1-alkynyl)chromones to produce a 3C-xanthone-linked 3C-chromone scaffold has been developed. This tandem process involves multiple reactions such as Michael additions/cyclizations under mild conditions without a transition metal catalyst and inert atmosphere.
  • CuBr-catalyzed cascade reaction of 2-substituted-3-(1-alkynyl)chromones to synthesize functionalized 3-acylfurans
    作者:Liping Huang、Feng Hu、Qingdong Ma、Youhong Hu
    DOI:10.1016/j.tetlet.2013.04.070
    日期:2013.6
    A highly efficient CuBr-catalyzed domino reaction of 2-substituted-3-(1-alkynyl)chromones to synthesize functionalized 3-acylfurans has been developed. The reaction is mild, environmentally friendly and easily handled without the necessity for dry solvents and inert atmosphere. (C) 2013 Elsevier Ltd. All rights reserved.
  • Phase Transfer Reagent Promoted Tandem Ring-Opening and Ring-Closing Reactions of Unique 3-(1-Alkynyl) Chromones
    作者:Yang Liu、Shiyu Jin、Liping Huang、Youhong Hu
    DOI:10.1021/acs.orglett.5b00721
    日期:2015.5.1
    promoted tandem ring-opening and ring-closing reaction of 3-(1-alkynyl) chromones has been developed. This process remarkably generates functionalized 3-acyl-2-substituted chromones. Interestingly, when 3-(hepta-1,6-diyn-1-yl)chromone derivatives are applied, a novel tetracyclic chromone scaffold can be obtained by a further intramolecular 4 + 2 cyclization.
