    摘要:
    Tetrabutyl ammonium fluoride (TBAF) was found to be capable of catalyzing the intramolecular hydroalkoxylation of 6-hydroxyhex-2-ynoates and 7-hydroxyhept-2-ynoates. The reaction could be used to prepare 2,5-substituted THF rings and 2,6-substituted THP rings. (C) 2011 Wei Yu. Published by Elsevier BY, on behalf of Chinese Chemical Society. All rights reserved.

    for the stereoselective assembly of the ring C subunit were developed. A Pd‐catalyzed tandem alkyne–alkyne coupling/6‐endo‐dig cyclization sequence was explored and successfully pursued in the synthesis of a dihydropyran ring system. Elaboration of this methodology ultimately led to a concise synthesis of the ring C subunit of bryostatins.

    indole‐based biaryls with bromoalkyl alkynes by using palladium/norbornene (Pd/NBE) cooperative catalysis. This reaction is realized through a sequence of Catellani‐type C−H alkylation, alkyne insertion, and indole dearomatization, by forming two C(sp2)−C(sp3) and one C(sp2)−C(sp2) bonds in a single chemical operation, thus providing a diverse range of pentacyclic molecules, containing a spiroindolenine fragment

    日期:2024.5.10
    A Pd-catalyzed highly regio- and stereoselective hydrocyanation was developed, providing a novel approach to the stereodivergent synthesis of β-cyano-substituted acrylates in good yields with a wide substrate scope. The judicious selection of ligands was crucial for elegant control over the stereodivergence. Furthermore, the success of the E-hydrocyanation hinges on the right matching of Pd and L1

  • Pd(II)-catalyzed intramolecular aminopalladation/direct C–H arylation under aerobic conditions: synthesis of pyrrolo[1,2-a]indoles
    作者:Tiffany Piou、Luc Neuville、Jieping Zhu
    DOI:10.1016/j.tet.2013.01.003
    日期:2013.6
    Heating a DMA/pivalic acid (v/v=4/1) solution of diversely substituted 6-(phenylamino)hex-2-ynoates in the presence of a catalytic amount of Pd(OAc)(2) under oxygen atmosphere afforded pyrrolo[1,2-a]indoles in moderate to good yields. A domino sequence involving intramolecular aminopalladation followed by C-H activation and reductive elimination was proposed to account for the observed bis-cyclization. (C) 2013 Elsevier Ltd.
