Reaction of dicyandiamide with series of amino acids afforded guanidinyl pyrazolones 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, respectively. Although reaction of dicyandiamide with urea, acetamide, bezamide, allantion, p‐aminobenzoic acid, sulphanilic acid, and adenine gave biguanides 20, 21, 22, 23, 24, 25, 26, respectively. All compounds have been characterized on the basis
具有串联的双氰胺反应氨基酸,得到吡唑啉胍2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,分别。虽然与脲,乙酰胺,bezamide,尿囊素,双氰胺的反应p氨基苯甲酸,对氨基苯磺酸,和腺嘌呤给双胍类20,21,22,23,24,25,26,分别。所有化合物均已根据IR和1 H-NMR进行了表征。
