Phenylalanine in which the methylene group is replaced by a sulfur atom could be a useful bioisostere for the design of HIV-protease inhibitors. Due to the chemical instability of hemiaminal intermediates, these bioisosteres have to be prepared from α-hydroxyglycine following specific synthetic routes. In this paper, we report the synthesis of sulfenylated phenylalanine bioisosteres 2 and 3, which represent two original building-blocks for peptide solid phase synthesis.
亚甲基被硫原子取代的苯丙氨酸可能是设计 HIV 蛋白酶抑制剂的有用生物等排体。由于半缩醛胺中间体的化学不稳定性,这些生物等排体必须按照特定的合成路线由α-羟基甘氨酸制备。在本文中,我们报道了磺酰化苯丙氨酸生物等排体2和3的合成,它们代表了肽固相合成的两个原始构建模块。
