Stereoselective synthesis of flavonoids. Part 4. Trans- and cis-dihydroflavonols

Epoxidation of a series of poly-oxygenated chalcones with H2O2 in the presence of poly-α-aminoacids yielded chiral aromatic oxygenated oxiranes in moderate to high optical yields. Lewis acid-catalysed phenylmethanethiol ringopening o

The first enantioselective synthesis of trans- and cis-dihydroflavonols

Epoxidation of a series of polyoxygenated chalcones with H2O2 in the presence of poly(α-amino acid) catalysts, followed by Lewis acid-catalysed phenylmethanethiol ring-opening and cyclization, afforded trans- and cis-dihydroflavonols
