endured retro-1,3-dipolar cycloaddition/recycloaddition reactions under thermal or catalytic conditions to regenerate the corresponding regioisomeric counterpart. In addition, DFT calculations were performed at the M062X/6-31++g(d,p) level of theory to unravel the origin of the reversal of regioselectivity and endo-stereoselectivity of the title 1,3-dipolar cycloaddition reactions. Upon treatment of Isatin
开发了一种有效的非对映选择性路线,通过( Z )-5-亚芳基-1,3的一锅三组分 [3 + 2] 环加成反应获得新型螺吡咯[1,2- a ] 异喹啉-羟吲哚骨架-噻唑烷-2,4-二酮、靛红衍生物和 1,2,3,4-四氢异喹啉 (THIQ)。有趣的是,该反应的区域选择性既取决于温度,也取决于溶剂,允许以优异的产率合成两种区域异构的内-二螺吡咯并[2,1- a ]异喹啉并吲哚。前所未有地,每个异构体二螺吡咯并[2,1- a ]异喹啉并吲哚都经受了逆1,3-偶极环加成/再环加成反应在热或催化条件下再生相应的区域异构体对应物。此外,在 M062X/6-31++g(d,p) 理论水平上进行了 DFT 计算,以解开标题 1,3-偶极环加成反应的区域选择性和内立体选择性逆转的起源。在用 ( Z )-4-arylidene-5-thioxo-thiazolidin-2-ones 作为偶极体处理靛红、THIQ
