Coupling of various acylated amino acid derivatives with (naphthalen-2-lyloxy)acetic acid (3) in the presence of 1-hydroxy-benzoteriazole (HOBt) and DCC afforded the new amides 6–12. Alternatively, the latter compounds were prepared from reaction of the corresponding hydrazide 5, via the azide-coupling method, with the acylated amino acid derivatives. Treatment of 6, 10–12 with N2H4ċH2O afforded the
在 1-羟基苯并三唑 (HOBt) 和 DCC 存在下,将各种酰化氨基酸衍生物与(萘-2-烯丙氧基)乙酸(3)偶联得到新的酰胺 6-12。或者,后一种化合物是通过相应的酰肼 5 与酰化氨基酸衍生物的反应通过叠氮化物偶联方法制备的。用 N2H4ċH2O 处理 6, 10-12 分别得到酰肼 13-16,作为合成肽衍生物的关键中间体。在 TMSOTf 存在下,作为受体的 12 与作为供体的糖基三氯亚胺酸酯 18 反应得到新的糖苷 19。评估了新化合物的抗 HIV-1、抗牛病毒性腹泻病毒 (BVDV) 和抗肿瘤活性。© 2005 Wiley Periodicals, Inc. 杂原子化学 16:148–222, 2005; 在线发表于 Wiley InterScience (www. interscience.wiley.com)。DOI 10.1002/hc.20082
