A doubly linked 4,6-dideoxy-D-j/ rgo-hexos-2-ulose residue was identified in the cardenolide glycoside (1) isolated from Asclepias curassavica stems, and a branched hexos-4-ulose derivative isolated from Pittosporum tobira flowers is covered in Chapter 14. Oxidation (MCPBAAleOH) of unsaturated derivative (2) (obtained by base treatment of methyl 3,4-0-isopropylidene-2,6-di-0-methyl-P-D-galactopyranoside) afforded L-arabino-hexos-S-ulose derivative (3) and then (4) after acid hydrolysis. The hexopyranosid-3-uloses (5) have been prepared by oxidation (Cr03/Ac20/pyridine) of the corresponding 3-alcohols. ... [Pg.180]
