摘要
2,3-二基-5,6-二氢吡嗪与醛或酮在氢氧化钠的乙醇溶液中反应制得16种5-烃基-2,3-二甲基吡嗪。产率66%~90%。其中6种为新合成的化合物。产率17%~87.9%。
The reaction of 2,3-dimethyl-5,6-dihydropyrazinewith aldehydes or ketones in sodium hydroxide/ethanol solu-tion gave sixteen corresponding 5-alkyl-2,3-dimethyl-pyrazines with yields of 66%~90%,approaching or higherthan that in sodium ethoxide/ethanol solution.Another sixnew compounds were synthesized by similar method withyields of 17%~87.9%.
