Diversification of 4′-Methylated Nucleosides by Nucleoside Phosphorylases [PDF]
The growing demand for 4'-modified nucleoside analogs in medicinal and biological chemistry is contrasted by the challenging synthetic access to these molecules and the lack of efficient diversification strategies. Herein, we report the development of a biocatalytic diversification approach based on nucleoside phosphorylases, which allows the ...

A rigid molecular clip comprising bisphosphonate binding sites and aromaticsidewalls forming an electron-rich cavity is able to distinguish between nucleosides andnucleotides in aqueous solution. Neutral nucleosides as well as antibiotics derived thereofare drawn into the unpolar interior of the cleft and lead to substantial upfield-shifts in the 1HNMR
