An efficient method for the solid-phase synthesis of mono-, di- and triureas from resin-bound monoamines, diamines and triamines is described. The exhaustive reduction of solid support-bound amides generated the requisite amines, which, following treatment with isocyanates and cleavage, provided the corresponding ureas in high purity and good yields.
描述了一种从树脂结合的单胺,二胺和三胺固相合成单,二和三脲的有效方法。固体载体结合的酰胺的彻底还原产生了必要的胺,这些胺在用异氰酸酯处理并裂解后,以高纯度和高收率提供了相应的脲。
