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.

2(3H)‐Furanones 1 were utilized for the construction of pyrrolinotriazine and oxazolopyrimidine derivatives 4 and 9. Thus, 1 reacted with glycine in ethanol at 70°C to give the acids 2, which were cyclized into the pyrrolin‐5‐one derivatives 3 by the action of HCl/AcOH. The later compounds 3 were also obtained by refluxing the furanones 1 with glycine in glacial AcOH for 10 h. The carboxy functionality

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.
