Regiospecific synthesis of 4-deoxy-D-threo-hex-3-enopyranosides by simultaneous activation-elimination of the talopyranoside axial 4-OH with the NaH/Im2SO2 system: Manifestation of the stereoelectronic effect

A new and high-yielding method for the regioselective preparation of 4-deoxy- and 2,4-dideoxy-2-acetamido-β-D-threo-hex-3-enopyranosides has been developed. The process involves a simultaneous activation-elimination of the OH-4 group of β-D-talopyranoside
