Tiwari,Secrist III,Montgomery
, p. 1819 - 1828 (1994)
1,2,3,5-Tetra-O-acetyl-4-thio-D-ribofuranose, prepared from 2,3,5-tri-O- benzyl-D-ribofuranose in four steps, was converted to the corresponding 2- chloroadenine nucleoside (8), which was deoxygenated to obtain 2-chloro-2'- deoxy-4'-thioadenosine (12). Th
