A green, regioselective protocol for the synthesis of thiopyrano[2,3‐d]thiazole‐2‐thiones catalyzed by basic ionic liquid [bmIm]OH has been developed. The reaction proceeds smoothly under microwave irradiation, and high yields of the products are obtained in very short reaction times (5–11 min). The ionic liquid plays a dual solvent‐catalyst role.
已经开发了一种绿色的区域选择性方案,用于在碱性离子液体[bmIm] OH催化下合成噻吩并[2,3 - d ]噻唑-2-硫酮。在微波辐射下,反应可顺利进行,并且在很短的反应时间(5-11分钟)内即可获得高产率的产物。离子液体起着双重溶剂催化剂的作用。
