title: Micro-flowers changing to nano-bundle aggregates by translocation of the sugar moiety in Janus TA nucleosides.
abstract: 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.
