✦ Synopsis

Photolysis of [~-cydodextrin inclusion complexes of 1-and 2-naphthyi esters (acetates and benzeat~) in aqueous metfium, results in ~ to give one isomer of acylnaphthol in excess, whereas the solid state irra~ation of the Β’yclodextrin ~ yields soleftivety otlg isomer. In addition, formation of cleavage product is totally ~, This remadralble scle~vity ia attrilmt~ to specific mocks of the complexation of the esters into the [~,CD cavity.

1-Naphthyl phenyl acylates upon irradiation in solution yield eight products via b-cleavage process. However, excitation of these molecules as included in g-cyclodextrin results in a single product (>95%). This medium dependent product selectivity is attributed to conformational and translational re
