通过 2-[双(甲硫基)亚甲基]茚满-1,3-二酮 (1) 与各自的脒衍生物 [碳酸胍 (2a)、盐酸乙脒 (2b)、S-甲基异硫脲硫酸盐 (2c)、和S-苄基异硫脲硫酸盐(2d)]。 4-取代的氨基-2-氨基茚并[1,2-d]嘧啶-5-酮(7b,7c,7d)是通过1,2a和各自的胺化合物(4b,4c,4d)在吡啶中的一锅反应合成的。这些稠合嘧啶衍生物在固态下显示出荧光。
New fluorescent compounds, 2‐substituted indeno[1,2‐d]pyrimidin‐5‐ones (3a,3b,3c,3d) were synthesized in good yield by the reaction of 2‐[bis(methylsulfanyl)methylene]indan‐1,3‐dione (1) with the respective amidine derivatives [guanidine carbonate (2a), acetamidine hydrochloride (2b),S‐methylisothiourea sulfate (2c), andS‐benzylisothiourea sulfate (2d)]. 4‐Substituted amino‐2‐aminoindeno[1,2‐d]pyrimidin‐5‐ones (7b,7c,7d) were synthesized by a one‐pot reaction of1,2aand the respective amine compounds (4b,4c,4d) in pyridine. These fused pyrimidine derivatives showed fluorescence in the solid state.
