本论文共分为四章:第一章对基于腙的化学进行简要的文献回顾;第二章讲述了基于t-BuOK促进的分子内环化反应合成3-三氟甲基吡唑和其它多取代吡唑的研究;第三章讲述通过PtCl4催化的[3,3]重排反应进行吡唑合成的研究;第四章讲述基于炔丙醇和苯肼腙为原料进行1,4-二氢哒嗪合成的研究。 第一章:腙是一类重要的合成底物,含有不同取代基的腙具有不同的反应位点。I)N,N-二取代腙,被称为第四类酰基阴离子等价合成子。在本章中,我们主要概述其参与的反应类型。II)N-Ts腙在碱的作用下,可以作为重氮的等价合成子。在本章中,我们主要介绍它原位生成重氮后所参与的一些反应。III)而对于炔丙基腙,由于其具有...The dissertation consists of four chapters. In the first part, the chemical reactionsbased on hydrazones will be briefly reviewed. In the second part, we will talk about our research on the synthesis of 3-trifluoromethylpyrazoles and polysubstituted pyrazoles via a t-BuOK mediated intramolecular cyclization. The third chapter describes the synthesis of polysubstituted pyrazoles by a platinum-catal...学位:理学博士院系专业:化学化工学院_有机化学学号:2052012015354
