Synthesis of 3,5-anhydro-2-deoxy-1,4-glyconolactones by palladium(II)-catalyzed, regioselective oxycarbonylation of C5- and C6-enitols. ω-Homologation of aldoses to produce intermediates for C-glycoside/C-nucleoside synthesis

The palladium(II)-catalyzed oxycarbonylation, known with alkenols and alkenediols, is studied with optically active 4-pentenitols (-triols) 1, 7 and 5-hexenitols (-tetrols) 12, 15, 18. Efficient routes for the substrates are provided, mostly from carbohyd
