An efficient synthesis of N,N'-substituted guanidine derivatives was developed via an aromatic sulfonyl-activated thiourea intermediate. The use of certain aromatic sulfonamides, such as PbfNH(2), as the key reagent to incorporate a TFA-labile guanidine protection group greatly facilitates solid-phase synthesis of N,N'-substituted guanidine compounds.
通过芳族磺酰基活化的硫脲中间体开发了N,N'-取代的胍衍生物的有效合成方法。使用某些芳香族磺酰胺,例如PbfNH(2),作为掺入TFA不稳定的胍保护基的关键试剂,极大地促进了N,N'-取代的胍化合物的固相合成。
