合成了一系列新的4-(芳基/杂芳基-2-基甲基)-6-苯基-2- [3-(4-取代的哌嗪-1-基)丙基]哒嗪-3(2H)-衍生物。化合物的结构通过IR,1 H NMR和质谱数据证实。评价所有化合物对五种不同来源的人类癌细胞系的细胞毒性。HeLa(宫颈),SKBR3(乳腺癌),HCT116(结肠),A375(皮肤)和H1299(肺)处于不同浓度,并测定了IC 50值。HCT116和HeLa对研究的化合物最敏感。其中之一显示出对SKBR3的中等细胞毒性。大多数化合物表现出良好至中等的活性。
An asymmetric [3+2] cycloaddition reaction ofN-2,2,2-trifluoroethylisatin ketimines and 3-alkenyl-5-arylfuran-2(3H)-ones was developed with 1 mol% thiourea–tertiary amine.

The conversion of the 2(3H)‐furanone into the oxazinone and pyrimidinone derivatives is studied. A 2‐(furan‐2‐ylmethylene)‐4‐oxo‐4‐phenylbutanoyl azide 3 was synthesized to carry out these conversions through its thermolysis in dry benzene and/or base‐catalyzed decomposition of this azide in the presence of different amines. The structures of all compounds were demonstrated from their spectral data

The acid hydrazides bearing furyl, pyrazolyl, and indolyl rings 2 condense with isatin to give the corresponding hydrazones 3. Ring closure of the latter in an HCl/AcOH mixture led to the construction of a new pyrrolinone ring 4. The hydrazides 2 condensed also with phthalic anhydride to give the corresponding pyridazinophthalazines 5.
