    日期:2010.9.17
    A base-promoted one-pot tandem reaction has been developed from 3-(1-alkynyl)chromones with various acetonitriles to afford functionalized amino-substituted xanthones 3 under microwave irradiation. This tandem process involves multiple reactions, such as Michael addition/cyclization/1,2-addition, without a transition metal catalyst. This method provides an efficient approach to build up natural product-like
    由3-(1-炔基)色酮与各种乙腈开发了碱促进的一锅串联反应,以在微波辐射下提供官能化的氨基取代的氧杂蒽3。该串联过程涉及多个反应,例如迈克尔加成/环化/ 1,2-加成,而没有过渡金属催化剂。该方法提供了一种有效的方法来快速建立类似天然产物的多样化的氨基取代的蒽酮骨架。

  • 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.

    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.
