A practical solid-phase synthesis that simply uses Rink amide resin as an amine component in reacting with aromatic isothiocyanates and aliphatic amines to generate disubstituted guanidines is described. No special linker or guanylation reagents are involved in this method. The product is obtained in a ‘traceless-linker’ fashion and in high yield and purity when an electron-deficient isothiocyanate
描述了一种实用的固相合成,该合成简单地使用Rink酰胺树脂作为胺成分与芳族异硫氰酸酯和脂族胺反应生成二取代的胍。此方法不涉及特殊的接头或鸟苷化试剂。当使用缺电子的异硫氰酸酯时,以“无痕连接剂”的方式获得产物,并以高产率和高纯度获得。
