Abstract
In present study, three series of 2,6-dihalogenated stilbene derivatives were designed, synthesized, and assayed for anti-inflammatory and cytotoxic activities. All 62 compounds showed potential anti-inflammatory activity in zebrafish model in vivo, and the installation of halogens and pyridines led to significant improved effects. Among them, DHS2u and DHS3u with the substitution of pyridine showed more higher effects than positive drug indomethacin at 20 μM with inhibitory rate of 94.59% and 90.54%, respectively. Besides, DHS3g bearing 2,5-dimethoxy exhibited potent cytotoxic activity against K562 cells with IC50 values 3.12 μM along with a suitable selectivity on normal cell viability. These results showed that 2,6-dihalogenated stilbenes could serve as a bright starting point for the further development as anti-inflammatory and antitumor agents.

Abstract
A representative condensation of acrylonitrile and aryl acetonitrile has been reported for the synthesis of α-amino-β-cyano cyclohexene. The reaction was carried out mildly in an open environment at room temperature. The scope and versatility of the method have been demonstrated with 20 examples, containing highly active ethynyl groups. Further applications for 4-aminopyrimidine compounds were performed. A mechanism was proposed, involving Michael additions between acrylonitrile and aryl acetonitriles as well as intramolecular condensation.
