R. Arad-yellin et al., Reversible encapsulation of guests in modified cyclodextrins: studies withthe beta-cyclodextrin percinnamate 1,7-dioxaspiro[5,5]undecane system, TETRAHEDR L, 42(7), 2001, pp. 1335-1337
UV irradiation of a solution of the pheromone 1,7-dioxaspiro[5,5]undecane (
DU) and beta -cyclodextrin percinnamate (beta -CD-PC) induces the formation
of intramolecular cyclobutane bridges that tray, the pheromone within the
cyclodextrin cavity. Release of the pheromone can be achieved by bond-break
ing chemical reactions, suggesting that such systems may be used for the co
ntrolled release of this or other pheromones under field conditions. (C) 20
