NEW SYNTHESIS OF BOTH D-3-O-CARBAMOYL-2-DEOXY-4-THIORIBOSIDES AND L-3-O-CARBAMOYL-2-DEOXY-4-THIORIBOSIDES, SUBSTRATES FOR BETA-SELECTIVE GLYCOSYLATIONS
S. Shawponter et al., NEW SYNTHESIS OF BOTH D-3-O-CARBAMOYL-2-DEOXY-4-THIORIBOSIDES AND L-3-O-CARBAMOYL-2-DEOXY-4-THIORIBOSIDES, SUBSTRATES FOR BETA-SELECTIVE GLYCOSYLATIONS, Tetrahedron letters, 37(11), 1996, pp. 1871-1874
A new route to intermediates for the synthesis of 2'-deoxy-4'-thionucl
eosides is described. By utilising enantiomeric erythro-dibenzyldithio
acetals, both D- and L-3-O-(N-acyl)carbamoyl thiosugars, which give be
ta-selective glycosylations, are readily produced.
