title: Synthesis of oligoribonucleotides containing 4-thiouridine using the convertible nucleoside approach and the 1-(2-fluorophenyl)-4-methoxypiperidin-4-yl group.
abstract: Oligoribonucleotides containing 4-thiouridine were prepared using the Fpmp group for protection of the 2'-OH. Two uridine derivatives with the 1,2,4-triazolyl and the 2-nitrophenyl groups at position 4 were used to obtain 4-thiouridine by postsynthetic substitution with sodium hydrogen sulfide. Both uridine derivatives allow the preparation of the desired oligonucleotides in good yields.
