heteroaryl glycosyl sulfones undergo desulfonylative C−C cross-coupling with aryl-substituted nucleophiles or electrophiles through two complementary catalytic systems. The reactions offer access to a wide variety of C-aryl glycoside products with high diastereoselectivity.

The lipase-mediatedkineticresolution of compound 1 was investigated to prepare chiral synthons showing oxygenatedstereotriads in a definiteconfigurational arrangement. These key intermediates were embedded in biologically relevant structures, such as hydroxylated pyrrolidine 3 and C-phenyl glycosides by classical organic reactions.
