1-dioxide (DCDBTSD) as a highly efficient and homogeneous catalyst was successfully applied for the synthesis of 4H-pyran, pyranopyrazole and pyrazolo[1,2-b]phthalazine derivatives by a one-pot multi-component reaction (MCR) in water. The described method has some advantages such as mild and neutral reaction media, high yields, short reaction times, cleaner and easier reaction profiles and compliance with
N,2-二溴-6-氯-3,4-二氢-2 H-苯并[ e ] [1,2,4]噻二嗪-7-磺酰胺1,1-二氧化物(DCDBTSD)作为高效且均相的催化剂通过一锅多组分反应(MCR)在水中成功地将其用于合成4 H-吡喃,吡喃并吡唑和吡唑并[1,2- b ]酞嗪衍生物。所描述的方法具有一些优点,例如温和和中性的反应介质,高收率,较短的反应时间,更清洁和更容易的反应过程以及符合绿色化学方案。
