Total asymmetric syntheses of d-lividosamine and 2-acetamido-2,3-dideoxy-d-arabino-hexose derivatives

The "naked sugar" (+)-(1R, 4R)-7-oxabicyclo[2.2.1]hept-5-en-one((+)-2) has been converted to D-lividosamine ((+)-1: 3-deoxy-D-glucosamine) and derivatives via (+)-2-chloro-2,3-dideoxy-5,6-O-isopropyridene-D-arabino-hexono-1,4-lactone ((+)-33) and (+)-2-az

THE ELECTRON-RELEASING HOMOCONJUGATED CARBONYL GROUP. APPLICATION TO THE TOTAL SYNTHESES OF 3-DEOXY-,4-DEOXY-HEXOSE,LIVIDOSAMINE AND DERIVATIVES

The regioselective electrophilic addition of benzeneselenyl bromide to (-)-(1S,4S)-7-oxabicyclo-hept-5-en-2-one were exploited to develop efficient syntheses of methyl 3-deoxy-α-D-arabino-hexofuranoside and 4-deoxy-D-lyxo-hexopyranose.Similarly, D-
