  CuBr-catalyzed cascade reaction of 2-substituted-3-(1-alkynyl)chromones to synthesize functionalized 3-acylfurans

  摘要：

  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

  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.

  已经开发出相转移试剂促进3-（1-炔基）色酮的串联开环和闭环反应。该过程显着产生官能化的3-酰基-2-取代的色酮。有趣的是，当使用3-（庚-1,6-二炔-1-基）色酮衍生物时，可以通过进一步的分子内4 + 2环化获得新型的四环色酮支架。
• 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

  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.

  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.
