- 中文摘要: Methylquinoxaline derivative 1 undergoes bromination to give bromomethyl quinoxaline 2, which could be transferred to cyanomethyl quinoxaline 3. The latter compound 3 readily coupled with arene diazonium salts to give hydrazone derivatives 5a-c. Compounds 5a,b reacted with active methylene reagents to give the target ring system, quinoxalinylpyridazine derivatives 8a-c. Compound 1 reacted with DMFDMA to give the enamine derivative 9, which coupled with arene diazonium salts to give the aldehydic hydrazone derivatives 10a-c. Compound 10 reacted with active methylene compounds to give quinoxalinylpyridazine derivatives. UV characterization of some of the prepared compounds was reported.
