A series of novel N-linked diglycose derivatives 9 and 10 were conveniently and directly synthesized based on the key step of one-pot tandem Staudinger/aza-Wittig/reduction reaction from the azido sugar and sugar-derived aldehyde followed by deprotection. The biological activities against glycosidases (alpha-amylase, alpha-glucosidase, and beta-glucosidase) and HIV-RT and antitumor activity of these
基于一叠串Staudinger / aza-Wittig /从叠氮基糖和糖衍生的醛还原反应然后脱保护的关键步骤,方便而直接地合成了一系列新颖的N-连接的二糖衍生物9和10。初步评估了它们对糖苷酶(α-淀粉酶,α-葡萄糖苷酶和β-葡萄糖苷酶)和HIV-RT的生物学活性以及抗肿瘤活性。
