Oligonucleotides containing 2'-deoxysangivamycin are described. The phosphoramidite of 2'-deoxytoyocamycin was prepared and used in solid-phase synthesis. Upon deprotection the pyrrolo[2,3-d]pyrimidine nitrile residues were converted to carboxamides. Acco

Treatment of unhindered secondary alcohols with phenoxythiocarbonyl chloride (phenyl chlorothionocarbonate) in pyridine/dichloromethane, or in acetonitrile with 4-dimethylaminopyridine catalysis for hindered alcohols, gave clean conversion to their O-phenoxythiocarbonyl derivatives. Reductive deoxygenation of these phenyl thionocarbonate esters proceeded smoothly, using tri-n-butyltin hydride and a free radical initiator in warm toluene. Overall conversion yields ranged from 57 to 78% for the naturally occurring nucleosides, nucleoside antibiotics, and methyl beta -D-ribofuranoside.
