D. Filippov et al., AN APPROACH TO THE SOLID-PHASE SYNTHESIS OF OLIGONUCLEOTIDES CONTAINING N-ACYLPHOSPHORAMIDATE INTERNUCLEOSIDIC LINKAGES, Synlett, (8), 1996, pp. 769
(2-Cyanoethoxy)(N,N-diisopropylamino) tyl)-beta-D-erythro-pentofuranur
on-amido)phosphine 7 was used as a building unit in a stepwise solid p
hase synthesis of an immobilized decamer employing 5-mercapto-1-methyl
tetrazole as activation reagent. Decyanoethylation and release of the
immobilized decamer from the support with methanolic potassium carbona
te furnished modified oligonucleotide 16.
