diversity-oriented synthesis of polyheterocyclic small-molecule library with privileged benzopyran substructure. To ensure the synthetic efficiency, we utilized the solid-phaseparallel platform and the fluorous-tag-based solution-phase parallel platform to construct a 284-member polyheterocyclic library with six distinct coreskeletons with an average purity of 87% on a scale of 5–10 mg. This library was designed

three‐component reaction was developed to construct a class of optically active carbazolespirooxindole‐urazoles in good yields with excellent stereoselectivities via tandem Diels‐Alder reaction and ene‐reaction. The driving force originating from aromatization with in situ generated carbazolespirooxindole and the high reactivity of 4‐phenyl‐3H‐1,2,4‐triazole‐3,5‐dione facilitate the ene‐reaction in mild conditions
通过串联Diels-Alder反应和烯反应,开发了一种设计良好的三组分反应,以高收率和优异的立体选择性构建了一类光学活性咔唑螺氧并吲哚-尿嘧啶。原位产生的咔唑螺硫醇芳香化作用产生的驱动力和4-苯基-3 H -1,2,4-三唑-3,5-二酮的高反应活性有助于在温和条件下进行烯反应。对照实验表明,烯反应的出色立体选择性很可能来自咔唑螺并恶唑的空间构型。所获得的产物可以通过多种功能化转化为其他合成有用的结构。
