With the help of Surflex-Dock calculation, two ritonavir analogs in which one thioazole unit was replaced by selenazole have been designed and synthesized. The key selenazole structure was constructed from β-azido diselenide through a cascade diselenide cleavage/selenocarbonylation/Staudinger reduction/aza-Wittig reaction and a following MnO₂ oxidation. The accordingly prepared compounds exhibited good anti-HIV-1 (IIIB) activities comparable to that of the original ritonavir, as well as the positive SI values.

亚硒唑取代的利托那韦类似物的设计与合成

借助于Surflex-Dock计算，已设计并合成了两个利托那韦类似物，其中一个硫唑单元被硒仑唑代替。通过级联二硒化物裂解/硒代羰基化/施陶丁格还原/氮杂-维蒂希反应和随后的MnO ₂氧化，由β-叠氮二硒化物构建关键的硒唑结构。相应制备的化合物显示出与原始利托那韦相当的良好的抗HIV-1（IIIB）活性，以及​​正的SI值。
