  The 5′,6-Oxomethylene Transglycosidic Tether for Conformational Restriction of Pyrimidine Ribonucleosides. Investigation of 6-Formyl- and 6-(Hydroxymethyl)uridine 5′-Carboxaldehydes

  摘要：

  In an effort to develop a new motif for the transglycosidic tethering of the pyrimidine nucleoside framework, the 2',3'-O-isopropylidenated and unprotected versions of 6-formyl- and 6-(hydroxymethyl)uridine 5'-carboxaldehyde were prepared and these were examined for their ability to adopt 5',6-oxomethylene tethered solution structures. In aqueous solution, the 2',3'-O-isopropylidenated nucleosides readily generated spiro-dihydrouridines via proximity-induced transglycosidic intramolecular reactions. In stark contrast, their unprotected counterparts existed mainly as the untethered aldehyde hydrates. Based on these findings, the 5',6-oxomethylene transglycosidic tether appears to constitute a useful conformational restriction motif for the pyrimidine ribonucleoside flamework, but only when the 5'-OH group is functionalized.

  The self-complementary UA and AU dinucleotide analogues 41–45, 47, 48, and 51–60 were prepared by Sonogashira coupling of 6-iodouridines with C(5′)-ethynylated adenosines and of 8-iodoadenosines with C(5′)-ethynylated uridines. The dinucleotide analogues associate in CDCl3 solution. The C(6/I)-unsubstituted AU dimers 51 and 54 prefer an anti-oriented uracilyl group and form stretched linear duplexes
