    • Conditions using Lewis acids and hemithioacetals, with no electrophilic activator of the hemithioacetals, were ineffective for the cyclisation of N-benzyl glyoxamides lacking electron-releasing groups on the benzene rings See the ESI for partial characterisation of the hemithioacetal and trifluoroacetylated hemithioacetal intermediates It appears likely that more Lewis acid and more forcing conditions were required for the cyclisation of these substrates as they contain alternative sites on the aromatic ring for Lewis acid coordination and deactivation For reviews of the Sharpless asymmetric dihydroxylation
