  • Cascade Nucleophilic Addition−Cyclic Michael Addition of Arynes and Phenols/Anilines Bearing Ortho α,β-Unsaturated Groups: Facile Synthesis of 9-Functionalized Xanthenes/Acridines
    作者:Xian Huang、Tiexin Zhang
    DOI:10.1021/jo902311a
    日期:2010.1.15
    A facile synthesis of xanthenes and acridines based on a cascade nucleophilic addition−cyclic Michael addition process of arynes and phenols/anilines substituted with α,β-unsaturated groups at the ortho positions is described. The reaction has also been successfully extended to the synthesis of 9-spiro-xanthene and acridine derivatives with potential biochemical interest.

  • A Facile Approach for Synthesis of Benzofuro[2,3-<i>c</i>]pyridines<i>via</i>Intramolecular Cascade Annulations
    作者:Ying Duan、Ye Wang、Dongmi Li
    DOI:10.1002/cjoc.201400364
    日期:2014.11
    A facile synthesis of benzofuro[2,3‐c]pyridines has been achieved under mild conditions by using ammonium acetate as the nitrogen source through intramolecular cascade annulation. This reaction could efficiently construct pyridine ring and furan ring in one step. Moreover, the key annulation step was demonstrated through dihydrobenzofuran intermediates.

  • Dually activated Michael-Michael-acetalization cascade: facile and highly diastereoselective construction of tetrahydro-6-hydroxyl-6H-benzo[c]chromen-9-one polycyclic scaffold
    作者:Jian Liu、Sai-Shuai Wen、Jing Wang、Jun-An Xiao、Shao-Jie Huang、Hua Yang
    DOI:10.1016/j.tet.2015.05.014
    日期:2015.7
    A Michael-Michael-acetalization cascade between 4-(2-hydroxyphenyl)but-3-en-2-ones and alpha,beta-unsaturated aldehydes via a novel dual activation mode promoted by pyrrolidine was successfully established. Consequently, various novel tetrahydro-6-hydroxyl-6H-benzo[c]chromen-9-one derivatives were prepared in excellent diastereoselectivities and moderate to good yields. Further diverse modification of the resulting tricyclic scaffolds provided a facile pathway to achieve a variety of tetrahydro-6-hydroxyl-6H-benzo[c]chromen-9-one analogs. (C) 2015 Elsevier Ltd.
