We designed and synthesized the Janus-type TA nucleosides (1–3) by using a transglycosylation protocol. Surprisingly, the subtle translocation of the ribose from N8 to N1 by about 230 pm in space leads to the formation of entirely different shaped superstructures, micro-flowers for J-AT and nano-bundles for J-TA.
我们采用转糖基化协议设计并合成了 Janus 型 TA 核苷(1-3)。令人惊讶的是,
核糖从 N8 到 N1 在空间上微妙地转移了约 230 pm,从而形成了形状完全不同的上层结构:J-AT 为微流,J-TA 为纳米束。
