  • gold catalyzed oxidative cyclizations of o alkynyl phenyl propargyl silyl ether derivatives involving 1 2 enynyl migration synthesis of functionalized 1h isochromenes and 2h pyrans
    Organic Letters, 2018
    Co-Authors: Jidong Zhao, Wei Xu, Xiangdong Li
    Abstract:

    A new and convenient strategy for the synthesis of functionalized 1H-Isochromene and 2H-pyran derivatives based on gold-catalyzed oxidative cyclizations of o-(alkynyl)phenyl propargyl ether derivatives has been developed. The reaction proceeds via gold-catalyzed highly regioselective oxidation, followed by 1,2-migration of an enynyl group and nucleophlic addition. Isocoumarins were also constructed through oxidative cleavage of the exocyclic double bond of the obtained 1H-Isochromenes.

  • one pot synthesis of 1h isochromenes and 1 2 dihydroisoquinolines by a sequential isocyanide based multicomponent wittig reaction
    Organic and Biomolecular Chemistry, 2016
    Co-Authors: Long Wang, Zhirong Guan, Mingwu Ding
    Abstract:

    A one-pot synthesis of 1H-Isochromenes and 1,2-dihydroisoquinolines by a I-MCR/Wittig sequence was developed. The reaction of phosphonium salt 5, an acid, an amine (or without), and an isocyanide gave the 1H-Isochromenes 7 or 1,2-dihydroisoquinolines 9 in good yields by a sequential Passerini or Ugi condensation and an intramolecular Wittig reaction in the presence of K2CO3.
