A series of novel 1-(4-phenylthiazol-2-yl)-1,4-dihydrothiochroman[4,3-c]pyrazole have been prepared by a three-component reaction of thiochromanone-3-carbaldehyde, phenacyl bromide, and thiosemicarbazide. The reaction was in one-pot and did not require any additional catalyst with moderate yields. This method provided several advantages such as environment friendliness and simple work-up procedure. The compounds were assayed for antifungal activity and some of the new compounds can be further utilized as lead compounds.
通过三组分反应,由硫色满酮-3-甲醛、苯乙酰溴和硫脲合成了一系列新型1-(4-苯并噻唑-2-基)-1,4-二氢硫代色满[4,3-c]吡唑。反应一步完成,无需额外催化剂,且产率适中。该方法具有环境友好性和操作简便等优点。所合成化合物经抗真菌活性测试,其中一些新型化合物可进一步作为先导化合物使用。
