A phosphoramidite (RO)2PNR2 is a monoamide of a phosphite diester. The key feature of phosphoramidites is their markedly high reactivity towards nucleophiles catalyzed by weak acids e.c., triethylammonium chloride or 1H-tetrazole. In these reactions, the incoming nucleophile replaces the NR2 moiety. WebHere, we report the preparation of two complete series of RNA nucleoside phosphoramidites; each has an appropriately protected amine or thiol functional group. The first series includes each of the four common RNA nucleotides, U, C, A, and G, with a 2′-(2-aminoethoxy)-2′-deoxy substitution (i.e., a primary amino group tethered to the 2 ... tax on loan interest income https://thebrummiephotographer.com
