RT info:eu-repo/semantics/article T1 Multicomponent Prins Cyclization from Allylsilyl Alcohols Leading to Dioxaspirodecanes A1 Barbero Pérez, María Asunción A1 Diez de la Varga, Alberto A1 Pulido Pelaz, Francisco José AB A multicomponent reaction for the preparation of dioxaspirodecanes starting from allylsilyl alcohols was achieved. The one-pot sequence involves the sequential acid-catalyzed reaction of an allylsilyl alcohol with an aldehyde to afford an alkenediol. The subsequent Prins cyclization of the homoallylic alcohol moiety generates a tetrahydropyranyl carbocation which is intramolecularly trapped by the second hydroxyl group. The chemoselectivity of the process shows dependence on the nature of the aldehyde and the concentration of the catalyst.
