Building Blocks for Oligonucleotide Analogues with Dimethylene Sulfide, Sulfoxide, and Sulfone Groups Replacing Phosphodiester Linkages

Huang, Zhen,Schneider, K. Christian,Benner, Steven A.

, p. 3869 - 3882 (2007/10/02)

Two routes are presented for the synthesis of 3',5'-bishomodeoxyribonucleosides, building blocks needed to synthesize oligodeoxynucleotide analogues where the OPO2O groups are replaced by CH2SCH2, CH2SOCH2, and CH2SO2CH2 units.Two of these have been coupl
