AbstractConditions for the Gewald synthesis of 2-amino-5,5-dimethyl-4,7-dihydro-5H-thieno[2,3-c]pyrans from 2,2-dimethyltetrahydropyran-4-ones have been optimized, and the yields have been improved. A procedure has been developed for the synthesis of new pyrano[4′,3′:4,5]thieno[2,3-b]pyridines by the Thorpe–Ziegler reaction of thieno[2,3-c]pyrans. Anticonvulsant activity of the synthesized compounds
摘要从2,2-二甲基四氢吡喃-4-酮中合成2-氨基-5,5-二甲基-4,7-二氢-5 H-噻吩并[2,3- c ]吡喃的Gewald条件得到了优化,产量得到提高。已开发了通过噻吩并[2,3 - c ]吡喃的Thorpe-Ziegler反应合成新的吡喃并[4',3':4,5]噻吩并[2,3- b ]吡啶的方法。研究了合成化合物的抗惊厥活性。
