New 6-(indol-3-yl)-5,6-dihydro-4H-1,3-thiazin-4-one derivatives were prepared by boron trifluoride catalyzed intramolecular cyclization of N'-substituted N-[3-(indol-3-yl)propenoyl]thioureas and by the reaction of 3-(indol-3-yl)propenoyl isothiocyanate with sodium hydrogensulfide. Antifungal activity of the prepared compounds was studied using the fungi Alternaria brassicae and Alternaria brassicicola.
通过硼三氟催化的N'-取代N-[3-(吲哚-3-基)丙烯酰基]硫脲内环化反应和3-(吲哚-3-基)丙烯酰异硫氰酸酯与氢硫酸钠反应的方法制备了新的6-(吲哚-3-基)-5,6-二氢-4H-1,3-噻唑-4-酮衍生物。使用真菌Alternaria brassicae和Alternaria brassicicola研究了制备化合物的抗真菌活性。
