synthesized through one-pot three-component coupling of terminal alkynes, sulfonyl azides, and thiols by using a copper(I) catalyst in the presence of 4-dimethylaminopyridine. The proposed reaction is characterized by mild reaction conditions and tolerance of diverse functional groups. Additionally, the crucial pharmacophore of 3,4-dihydroquinazolines was synthesized using a one-pot synthetic strategy
在 4-二甲氨基吡啶存在下,使用铜 ( I ) 催化剂,通过末端炔烃、磺酰叠氮化物和硫醇的一锅三组分偶联,可以有效地合成N-磺酰硫亚胺。所提出的反应的特点是反应条件温和,对多种官能团具有耐受性。此外,3,4-二氢喹唑啉的关键药效团是使用N-磺酰硫代亚胺酸盐的一锅合成策略合成的。
