An efficient and regioselective three‐component heteroarylation‐nitration of alkenes with imidazo[1,2‐a ]pyridines and tert ‐butyl nitrite has been developed. The process tolerants a variety of functional groups under mild conditions in the absence of catalysts and additives to give nitro functionalized imidazo[1,2‐a ]pyridine derivatives in moderate to good yields. The reaction is also applicable for some other aza‐heterocycles.

咪唑并[1,2-a]吡啶和亚硝酸叔丁酯对烯烃的轻度和区域选择性三组分杂芳基化硝化

已经开发了一种高效的区域选择性烯烃三元杂芳基硝化硝化反应，该硝化反应包括咪唑并[1,2- a ]吡啶和亚硝酸叔丁酯。在没有催化剂和添加剂的条件下，该工艺可在温和条件下耐受各种官能团，从而以中等至良好的收率得到硝基官能化的咪唑并[1,2- a ]吡啶衍生物。该反应也适用于其他一些氮杂杂环。
