以2,3-二氯-1,4-萘醌为主要原料,分别与吗啡啉和糠胺在一定条件下反应生成2种含杂环的氨基萘醌类化合物。2,3-二氯-1,4-萘醌与吗啡啉及2,3-二氯-1,4-萘醌与糠胺物质的量比均为1∶2,反应温度为60℃,溶剂为乙醇。2,3-二氯-1,4-萘醌与吗啡啉反应时间为1 h,产物2-氯-3-吗啡啉基萘-1,4-二酮(a)收率为93.5%;2,3-二氯-1,4-萘醌与糠胺反应时间为4 h,产物N~2,N~3-二(2-呋喃甲基)-1,4-二((2-呋喃甲基)亚胺)-1,4-二氢化萘-2,3-二氯化铵(d)收率为46.7%。对产物进行IR、Uv、MS和H-NMR等分析表征。
2,3-Dichloro-1,4-naphthoquinone as the main raw material, respectively, morphine and furfuryl amine reaction under certain conditions to generate two heterocyclic naphthoquinone compounds. The ratio of 2,3-dichloro-1,4-naphthoquinone to morpholine and 2,3-dichloro-1,4-naphthoquinone to furfurylamine were all 1: 2, the reaction temperature was 60 ℃, the solvent For ethanol. The reaction time of 2,3-dichloro-1,4-naphthoquinone with morpholine was 1 h. The yield of 2-chloro-3-morpholinyl naphthalene-1,4-dione was 93.5% , The reaction time of 3-dichloro-1,4-naphthoquinone with furfuryl amine was 4 h, and the products N 2, N 3 -bis (2-furylmethyl) Yl) imine) -1,4-dihydronaphthalene-2,3-diammonium chloride (d) in a yield of 46.7%. The products were characterized by IR, Uv, MS and H-NMR.
