SYNTHESIS OF 2',3'-DIDEOXY-D-ERYTHRO-HEX-2'-ENOPYRANOSYL NUCLEOSIDES FROM 5-AMINOURACILS AND 3,4,6-TRI-O-ACETYL-D-GLUCAL

Pedersen, Henrik,Pedersen, Erik B.,Nielsen, Carsten M.

, p. 265 - 272 (2007/10/02)

Condensation of silylated N,N-disubstituted aminouracils (4) and 3,4,6-tri-O-acetyl-D-glucal (3) in the presence of TMS triflate as catalyst gave anomeric mixtures of 2',3'-dideoxy-D-erythro-hex-2'-enopyranosylnucleosides (5) and (6).The pure β- and α-ano
