underexploited for C8 modifications of these nucleosides. Only in situ formation of 8-formyladenosine is known and a single application of an N-benzoyl derivative has been reported. On the other hand, 8-formyl-2′-deoxyadenosine and its applications remain unknown. Herein, we report straightforward, scalable syntheses of both N-unprotected 8-formyladenine nucleoside derivatives, and demonstrate broad diversification
腺苷和 2'-脱氧腺苷的潜在用途广泛的N-未保护 8-甲酰基衍生物在这些核苷的 C8 修饰方面开发不足。只有8-甲酰腺苷的原位形成是已知的,并且已经报道了N-苯甲酰基衍生物的单一应用。另一方面,8-甲酰基-2'-脱氧腺苷及其应用仍然未知。在这里,我们报告了两种N-未保护的 8-甲酰腺嘌呤核苷衍生物的直接、可扩展的合成,并通过羟甲基化、叠氮化、CuAAC 连接、还原胺化以及改性 Julia 和霍纳的烯化和氟烯化证明了 C8 位的广泛多样化–Wadsworth–Emmons 试剂。
