R. Robles et al., AN EFFICIENT AND HIGHLY STEREOSELECTIVE SYNTHESIS OF NUCLEOSIDE DERIVATIVES FROM FURANOID 1,2-DIOLS, Tetrahedron : asymmetry, 8(17), 1997, pp. 2959-2965
Reaction between suitably protected furanoid glycals 1b-4b, readily ob
tained from furanoid 1,2-diols (1a-4a), and different silylated pyrimi
dine bases, gave the corresponding 3',5'- and 3',5',6'-O-protected 2'-
deoxy-2'-iodo-beta-D-xylo-pentofuranosyl 5-10 and beta-D-gluco-hexofur
anosyl 11 nucleosides, respectively. Compound 5 has been transformed i
nto its 2'-deoxy 12 and 2',3'-anhydro 14 derivatives. The high stereos
electivity of the reaction is discussed. (C) 1997 Elsevier Science Ltd
