CARDIAC GLYCOSIDES: 5. STEREOSELECTIVE SYNTHESES OF DIGITOXIGENIN alpha-D, beta-D, alpha-L AND beta-L-GLUCOSIDES
As part of a continuing study of cardiac glycosides, stereoselective syntheses of the four possible glucosides of digitoxigenin were developed via the thermodynamically produced tetra-O-benzyl-D- and L-glucosyl alpha-trichloroacetaimidates 2alpha and 11alpha, and the kinetically produced beta-trichloroacetaimidates 2beta and 11beta.A 58percent:19percent isolated yield ratio of alpha-D and beta-D benzyl protected glycosides 6 and 3 could be obtained in 30 minutes reaction at -10 deg.Halide ion catalysis with a 2:1 excess of tetra-O-benzyl-alpha-D-glucopyranosyl bromide for 14 days in methylene chloride at room temperature gave a 39percent:11percent ratio of 6 and 3, along with 43percent of recovered digitoxigenin.Debenzylation of the D-glucosides required milder conditions (20percent Pd/C, atmospheric pressure, 45 min – 1 hr) than the L-glucosides (40percent Pd/C, 2 hr) but yields were typically 80percent for both groups.
Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law.COA of Formula: C36H36Cl3NO6. In my other articles, you can also check out more blogs about 74808-09-6
