Abstract
Reaction of the bromosugars 2,3,4,6-tetra-O-acetyl-alpha-D-galactopyra nosyl bromide (1), methyl 2,3-anhydro-6-bromo-6-deoxy-alpha-D-allopyra noside (2), and methyl 4-O-benzoyl-6-bromo-6-deoxy-alpha-D-allopyranos ide (3) with the-allylic sulfides and sulfones 4-9 in the presence of hexabutyldistannane under photolytic conditions gave the corresponding alpha-C-allyl galactosides 10-12 and the 6-C-allylated epoxysugars 13 , 15, and 16 in 61-90% yield.
