以咪唑鎓盐、氯化钯和吖啶等为起始原料,经一锅法反应方便地合成了两种新颖的N-杂环卡宾-钯(Ⅱ)化合物.新化合物通过1H NMR,13C NMR和元素分析等手段进行了结构表征,结构通过X射线单晶衍射进行了确定.此外,所获得的钯(Ⅱ)化合物可以作为芳基或苄基氯化合物与芳基硼酸的Suzuki-Miyaura偶联反应高效催化剂.在优化的反应条件下,所有拓展的底物都能成功地发生反应,并得到较好的收率.

Nine new heterozygous isatin-quinazoline compounds were synthesized from cheap and easily available ortho nitrobenzaldehyde as the starting material.The chemical structures of the synthesized compounds were characterized by NMR,IR and HRMS.The structure of (E)-3-(((E)-(5-(4-((3-ethynylphenyl) amino) quinazolin-6-yl) furan-2-yl) methylene) hydrazono)-indolin-2-one (4a) was further determined by crystallization and X-ray diffraction,and the data revealed that its cis-trans isomerism was (E,E).The antitumor activity of these new compounds was evaluated in vitro by methyl thiazolyl tetrazolium (MTT) assay in human colorectal carcinoma cells SW480,human non-small cell lung cancer cells A549 and NCI- H1975,and human epidermoid squamous carcinoma cells A431.The preliminary data demonstrated that most of the synthetic compounds had moderate to potent inhibitory activity against these four tumor cell lines.In particular,compound 4a had highly potent inhibitory activity on proliferation of four cell lines,and the activity was more potent than positive lapatinib.
