clay and HY‐zeolite, have been employed efficiently for synthesis of 2‐amino 3‐cyano pyridines 4a, 4b, 4c, 4d, 4e, 4f, 4g, 4h, 4i, 4j, 4k, 4l, 4m, 4n, 4o, 4p, 4q, 4r, 4s, 4t, 4u, 4v, 4w, 4x by multicomponent reaction of 3‐acetyl 4‐hydroxy coumarin 1a, 1b, 1c, 1,3‐diphenyl‐1H‐pyrazole‐4‐carbaldehyde 2a, 2b, 2c, 2d, 2e, 2f, 2g, 2h, malononitrile 3, and ammonium acetate. Both the catalysts are recoverable
Fe 3+ K-10蒙脱土和HY沸石这两种固体酸已被有效地用于合成2-氨基3-氰基吡啶4a,4b,4c,4d,4e,4f,4g,4h,4i,4j,4k,4l,4m,4n,4o,4p,4q,4r,4s,4t,4u,4v,4w,4X由3-乙酰-4-羟基香豆素的多组分反应1A,1B,1C,1,3-二苯基-1- ħ吡唑-4-甲醛图2a,图2b,图2c,2d中,2E,2F,2克,2H,丙二腈3,乙酸铵。两种催化剂都是可回收的和可再循环的。该程序的主要意义是反应时间短,产率高,后处理程序容易并且对环境友好。所有化合物的结构均已通过IR,1 H NMR,13 C NMR和质谱数据。筛选所有合成的化合物的抗微生物和抗真菌活性。
