摘要

Several polysulfides were tested as potential sulfur-transfer reagents during the automated synthesis of oligodeoxyribonucleoside phosphorothioates via the" deoxyribonucleoside phosphoramidite" approach. The thiosulfonate 3H-1, 2-benzodithiol-3-one 1, l-dioxide (12) was particularly efficient as a sulfurizing reagent. A 0.2 M solution of 12 in acetonitrile converted the dinucleoside monophosphite triesters 13a-d into the corresponding ...
