dcterms:description
A series of flavin-cyclodextrin conjugates has been prepared and tested in enantioselective oxidations of prochiral aromatic and aliphatic sulfides with hydrogen peroxide. The newly prepared conjugates contain isoalloxazinium or alloxazinium moieties attached to primary rim of alfa- and beta-cyclodextrins at C-6 positions. In addition, flavinium units were appended to secondary rim of beta-cyclodextrin macrocycle. The relationship between structural features and catalytic performance of the conjugates, including those reported recently by us, was analysed. The rate and enantioselectivity of sulfoxidations catalyzed by flavin-cyclodextrin conjugates is influenced mainly by size of cyclodextrin cavity, type of flavin unit (alloxazine or isoalloxazine) and by relative orientation of flavin and cyclodextrin moieties.
