Blocked isocytosine isocyanates are conveniently obtained by the reaction of 1,1′-carbonyldiimidazole (CDI) with isocytosines. The resulting precursors for quadruple hydrogen-bonded structures can be isolated and stored for further use. Reaction with either aliphatic or aromatic amines gives the corresponding mono-, bi-, or trifunctional ureidopyrimidinone derivatives in good to excellent isolated
封闭的异胞嘧啶异氰酸酯可通过 1,1'-羰基二咪唑 (CDI) 与异胞嘧啶反应方便地获得。产生的四重氢键结构的前体可以被分离和储存以供进一步使用。与脂肪族或芳香族胺反应得到相应的单-、双-或三官能脲基嘧啶酮衍生物,分离产率良好至极好。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2004)
