D. Yu et al., DIETHOXY N,N-DIISOPROPYL PHOSPHORAMIDITE AS AN IMPROVED CAPPING REAGENT IN THE SYNTHESIS OF OLIGONUCLEOTIDES USING PHOSPHORAMIDITE CHEMISTRY, Tetrahedron letters, 35(46), 1994, pp. 8565-8568
The use of diethoxy N, N-diisopropyl phosphoramidite (DDP) as a cappin
g reagent for the synthesis of oligonucleotides, in conjunction with p
hosphoramidite chemistry, results in overall improvement in quality an
d yield.
