Sulfur-Based Synthesis Techniques

Abstract D-Psico- and D-sorbo-furanosyl derivatives 3 and 6 were synthesized in two steps through the methylenation of the D-ribono- and D-xylono-lactones 1 and 4 with dicyclopentadienyldimethyltitanium, followed by the cis-dihydroxylation of the resultant olefins 2 and 5 with catalytic osmium tetroxide and 4-methylmorpholine N-oxide.
