Synthesis of Pyrrolidine C-Nucleosides via Heck Reaction
摘要:
[GRAPHICS]A novel method for the synthesis of pyrrolidine C-nucleosides has keen developed, The key step of the synthesis is the palladium(0)-mediated coupling of a disubstituted N-protected 2-pyrroline and 5-iodouracil. C-Nucleoside 14 and its N-methyl derivative 15 can easily be convened to the corresponding phosphoramidite building blocks for DNA synthesis.

We synthesized pyrrolidino-C-nucleosides, incorporated them into oligodeoxynucleotides and investigated their pairing properties. The thermal duplex and triplex stabilities were measured. While triplex formation is destabilized in the case of pyrrolidino-pseudo-U and -T, pyrrolidino-pseudo-iso-C leads to an increase of the T-m value for third strand dissociation. Duplexes Lire destabilized with all pyrrolidino-C-nucleosides.
