Abstract
The conversion of four 5'-O-(4,4'-dimethoxytrityl)-2'-deoxyribonucleoside 3 '-H-phosphonates 1 (B=4, 5, 6 and 7) into their partially-protected nucleos ide precursors 3 (B=4, 5, 6 and 7, respectively) in good isolated yields is described. The procedure used is also suitable for the dephosphonylation o f protected oligonucleotide H-phosphonate blocks. (C) 1999 Elsevier Science Ltd. All rights reserved.
