An improved and simplified procedure for the attachment of nucleosides onto long chain alkylamine controlled pore glass beads (LCAA-CPG) is presented. This procedure uses 1-(3-dimethylamino-propyl)-3-ethylcarbodiimide (DEC) to couple nucleoside 3'-succinates directly to the LCAA-CPG. The preparation of nucleoside 3'-succinate anhydrides, p-nitrophenyl, or(More)
The chemical synthesis of oligoribonucleotides containing vicinal (2'-5')- and (3'-5')-phosphodiester linkages is described. The solid-phase method, based on silyl-phosphoramidite chemistry, was applied to the synthesis of a series of branched RNA [(Xp)nA2' (pN)n3'(pN)n] related to the splicing intermediates derived from Saccharomyces cerevisiae rp51a(More)
31P cross polarization (CP) magic angle spinning (MAS) nuclear magnetic resonance (NMR) spectra were acquired for various linear and branched di- and tri-nucleotides attached to a controlled pore glass (CPG) solid support. The technique readily distinguishes the oxidation state of the phosphorus atom (phosphate versus phosphate), the presence or absence of(More)
