Mr. Conte et al., AUTOMATED SYNTHESIS OF CYCLIC OLIGODEOXYRIBONUCLEOTIDES VIA PHOSPHORAMIDITE METHOD, Nucleosides & nucleotides, 12(3-4), 1993, pp. 351-358
The functionalized polyethylene glycol/polystyrene copolymer support 4
was shown to be suitable for a completely automated synthesis of smal
l- to medium-sized cyclic oligodeoxyribonucleotides. Syntheses of the
linear precursors were achieved by the phosphoramidite method, whereas
the cyclization reactions were based on the phosphotriester chemistry
.
