An efficient method for the preparation of 1′α-branched-chain sugar pyrimidine ribonucleosides from uridine: The first conversion of a natural nucleoside into 1′-substituted ribonucleosides

The 1′α-phenylselenouridine derivative 13 was successfully synthesized by enolization of the 3′,5′-O-TIPDS-2′-ketouridine 8, and was subjected to a radical reaction with a vinylsilyl tether - an efficient procedure for preparing 1′α-branched-chain sugar p

Synthesis of a 1'-α-phenylselenouridine derivative as a synthetic precursor for various 1'-modified nucleosides, via enolization at the 1'- position of 3',5'-O-TIPDS-2'-ketouridine

Synthesis of the 1'-α-phenylselenouridine derivative 1α, a potentially useful precursor for the synthesis of a variety of 1'-modified nucleosides, was achieved via enolization of the 3',5'-O-TIPDS-2'-ketouridine 2. Successive treatment of 2 with LiHMDS and PhSeCl at ≤70°C in THF gave the corresponding 1'-phenylseleno product, which was reduced stereoselectively with NaBH4/CeCl3 in MeOH to give the target compound 1α.
