摘要

本文报道了一种快速、高效、简单的超声辅助合成苯并噻唑-硒唑骨架的方法,该方法由异氰酸酰基(硒或硫)、苯并噻唑和各种末端炔在铜催化剂附近的一锅反应中合成,无需额外的配体,超声条件下反应45 min,效率很高。超声波在该反应中的作用是减少了时间,提高了产品制备的效率,并使后续工作更容易。采用简单易得的原料,温和的铜催化反应条件,易于溶剂纯化,最后从苯并噻唑-硒化唑族中合成了10个新的化合物是该方案的显著特点。

A facile synthesis of tricyclic compounds consisting of benzo thiazol-selenazol skeletons via the copper‐catalyzed four-component reactions
A rapid, efficient, and simple ultrasonic-assisted protocol is reported for the synthesis of benzo thiazol-selenazol skeletons from the one-pot reactions of acyl iso (seleno or thio) cyanate, benzothiazole and various terminal alkynes, in the vicinity of a copper catalyst, without the help of additional ligands under ultrasonic conditions for 45 min with good efficiency. The role of ultrasound in this reaction is to reduce the time, increase the efficiency of product preparation, and make the work-up easier. The use of simple and available raw materials, mild copper catalytic reaction conditions, easy purification with the help of a solvent, and finally, the synthesis of 10 new compounds from the benzo thiazol-selenazol family are notable features of this protocol.
