An efficient conversion from commercially available 2,6-diaminopurine-2′,3′,5′-tri-O-benzyl arabinoside to arabinosylguanine and its further transformation to 2′-deoxy-2′-fluoro-guanosine is outlined. This process has been used to produce more than one hundred grams of final product. Copyright
Uniformly modified 2'-deoxy-2'-fluoro phosphorothioate oligonucleotides as nuclease-resistant antisense compounds with high affinity and specificity for RNA targets

'Uniformly' modified phosphodiester or phosphorothioate oligonucleotides incorporating 2'-deoxy-2'-fluoroadenosine, -guanosine, -uridine, and - cytidine, reported herein for the first time, when hybridized with RNA afforded consistent additive enhancement of duplex stability without compromising base-pair specificity. CD spectra of the 2'-deoxy-2'-fluoro- modified oligonucleotides hybridized with RNA indicated that the duplex adopts a fully A-form conformation. The 2'-deoxy-2'-fluoro-modified oligonucleotides in phosphodiester form were not resistant to nucleases; however, the modified phosphorothioate oligonucleotides were highly nuclease resistant and retained exceptional binding affinity to the RNA targets. The stabilizing effects of the 2'-deoxy-2'-fluoro modifications on RNA-DNA duplexes were shown to be superior to those of the 2'-O-methylribo substitutions. RNA hybrid duplexes with uniformly 2'-deoxy-2'-fluoro-modified oligonucleotides did not support HeLa RNase H activity; however, incorporation of the modifications into 'chimeric' oligonucleotides has been shown to activate mammalian RNase H. 'Uniformly' modified 2'-deoxy-2'-fluoro phosphorothioate oligonucleotides afforded antisense molecules with (1) high binding affinity and selectivity for the RNA target and (2) stability toward nucleases.

2'-Deoxy-2'-fluoroguanylyl-(3'-5')-uridine (GfpU) was synthesized as a non-hydrolyzable substrate analog of ribonuclease T1. 2'-Deoxy-2'-fluoroguanosine was derivatized to the N2-isobutyryl-5''-monomethoxytrityl compound and condensed with 2',3'-di-O-acetyluridine 5'-monophosphate by the use of dicyclohexylcarbodiimide to obtain GfpU.For structural elucidation of the dinucleoside monophosphate, 2'-deoxy-2'-fluoroguanosine 3'-monophosphate was also synthesized.The conformation of GfpU was found to take a right-handed, weakly stacked form as deduced by ultraviolet, circular dichroism, and nuclear magnetic resonance (NMR) spectroscopy.Keywords--N2-isobutyryl-2'-deoxy-2'-fluoroguanosine; N2-isobutyltyl-5'-monomethoxytrityl-2'-deoxy-2'-fluoroguanosine; UV, CD, NMR, TLC; PPC
