  • Synthesis of 1,3,4-oxadiazolium and 1,3,4-oxadiazolo[3,2-a]pyridinium salts
    作者:G. V. Boyd、S. R. Dando

    is described. Numerous 3-aryl-1,3,4-oxadiazolium salts, containing a novel type of heterocyclic cation, have been prepared by the action of carboxylic anhydrides on diacylarylhydrazines in the presence of perchloric or fluoroboric acid. 1,3,4-Oxadiazolo[3,2-a]pyridinium salts are similarly formed from 1 -acylamino-2-pyridones. The stability of the salts and their i.r. and n.m.r. spectra are discussed
    已经研究了一些简单的1,3,4-恶二唑的质子化和烷基化,并描述了一种新的1,3,4-恶二唑的合成。在高氯酸硼酸的存在下,通过羧酸酐对二酰基芳基的作用,已经制备了许多含有新型杂环阳离子的3-芳基-1,3,4-恶二唑鎓盐。类似地由1-酰基基-2-吡啶酮形成1,3,4-氧杂二唑[3,2- a ]吡啶鎓盐。讨论了盐的稳定性及其ir和nmr光谱。

    日期:2017.9.1
    A modular, selective approach to complex α-tertiary substituted malononitriles is reported. The method takes advantage of β-ester-substituted α,α-dinitrile alkenes as highly reactive, chemoselective electrophiles for 1,4-additions with organometallic nucleophiles to produce functionally and sterically dense all-carbon quaternary centers. In the presence of a chiral ester auxiliary bearing an aromatic
    报道了一种复杂的α-叔取代丙二腈的模块化,选择性方法。该方法利用β-酯取代的α,α-二不饱和烯烃作为有机属亲核试剂进行1,4-加成的高反应性,化学选择性亲电试剂,可产生功能上和空间上均密集的全碳四元中心。在带有芳香环的手性酯助剂的存在下,由于有利的阳离子-π相互作用,发生了1,4-加成,选择性好至极好。高度官能化的丙二腈代表了多种构建基块,可用于高效,高度选择性的5,5-二取代吡咯嘧啶酮的合成。
