A practical synthesis of thiourea-linked peptidomimetics, glycosylated amino acids, and neoglycoconjugates is described employing bis(benzotriazolyl)methanethione as thiocarbonylating reagent. The entire protocol is mild, efficient, high-yielding, and free from hazardous reagents. All the intermediates and products have been isolated and fully characterized by ¹H NMR, ¹³C NMR, and mass spectrometry.
本文描述了一种实用的硫脲连接肽模拟物、糖基化氨基酸和新生糖缀合物的综合合成方法,采用双(苯并三唑基)甲烷硫酮作为硫羰基化试剂。整个方案温和、高效、产率高,并且不含危险试剂。所有中间体和产物均已分离并通过¹H NMR、¹³C NMR 和质谱完全表征。
