  • Expeditious and Efficient Synthesis of Benzoxazoles, Benzothiazoles, Benzimidazoles Catalyzed by Ga(OTf)3 under Solvent-Free Conditions
    作者:Juyan Liu、Qian Liu、Wei Xu、Weilu Wang
    DOI:10.1002/cjoc.201180310
    日期:2011.8
    new and efficient method for the synthesis of benzoxazoles, benzothiazoles, benzimidazoles from reactions of o‐substituted aminoaromatics with orthoesters in the presence of catalytic amounts of Ga(OTf)3 under solvent‐free conditions is presented. The remarkable features of this new protocol are high conversion, very short reaction times, cleaner reaction profiles under solvent‐free conditions, straight

    日期:2011.10
    Tertiary amines can be used in place of aldehydes and carboxylic derivatives as partners in the synthesis of benzimidazoles. Dehydrogenative amine activation under heterogeneous catalysis was developed for the direct transformation of tertiary amines into benzimidazoles. Good yields and efficient recovery and recycling of the catalyst are some of the advantages of this new methodology, which shows
