title: Probing the mechanism of Prins cyclisations and application to the synthesis of 4-hydroxytetrahydropyrans.
abstract: Trapping intermediates on the Prins cyclisation pathway with carbon-based nucleophiles has given further insight into factors affecting the acid-mediated reactions of homoallylic alcohols with aldehydes, enabling the design of efficient syntheses of 4-hydroxy-2,6-disubstituted tetrahydropyrans.
