Rp. Iyer et al., IMPROVED PROCEDURE FOR THE DETRITYLATION OF DMT-OLIGONUCLEOTIDES - USE OF DOWEX(R), Synthetic communications, 25(22), 1995, pp. 3611-3623
Dowex(R) resin (H+ form) is a convenient reagent for detritylation of
5'O-DMT-oligonucleotides. With Dowex, detritylation is rapid and quant
itative compared to that with acetic acid. As the liberated dimethoxyt
rityl species remain bonded to the resin, further processing of oligon
ucleotides is simplified.
