Abstract

A highly regio-and stereoselective asymmetric synthesis of rhamnosyl-and amicetosyl- digitoxigenin analogues has been established via palladium-catalyzed glycosylation followed by bis-/tris-dihydroxylation or bis-/tris-diimide reduction. The α-l-rhamnose and α-l- amicetose digitoxin monosaccharide analogues displayed stronger apoptosis inducing activity and cytotoxicity against nonsmall cell human lung cancer cells (NCI-H460) than its ...
