H. Aitsir et al., SYNTHESIS AND CONFIGURATIONAL ASSIGNMENTS OF 3-SUBSTITUTED 2-DEOXY-4-THIO-D-ERYTHRO-PENTOFURANOSE DERIVATIVES, Journal of the Chemical Society. Perkin transactions. I, (14), 1996, pp. 1665-1671
A new route is described to -2-deoxy-4-thio-alpha,beta-D-erythro-pento
furanose derivatives starting from L-arabinose. This route is amenable
to variation in the 3-substituent and the 3-O-benzoyl and 3-azido der
ivatives were obtained in 17 and 15% yields, respectively, making this
procedure easily the most economical entry to 4'-thionucleosides. The
anomeric configuration of these and other thiosugars is established u
nequivocally.
