"Four structurally different alloxazine\u2013cyclodextrin conjugates were prepared and tested as catalysts for the enantioselective oxidation of prochiral sulfides to sulfoxides by hydrogen peroxide in aqueous solutions. Alpha-cyclodextrin conjugate having alloxazinium unit attached via a short linker proved to be a suitable catalyst for oxidations of n-alkyl methyl sulfides, displaying conversions up to 98% and enantioselectivities up to 77% ee. Beta-cyclodextrin conjugates were optimal catalysts for the oxidation of sulfides carrying bulkier substituents; e.g. tert-butyl methyl sulfide was oxidized with quantitative conversion and 91% ee. Low loadings (0.3\u20135 mol%) of the catalysts were used." . "[F65722A0B0FD]" . "10.1039/c1ob05934c" . "185239" . "P(GA203/07/1246), P(GA203/09/1919), Z(AV0Z40550506)" . "4"^^ .
