Abstract
A copper(II) trifluoromethanesulfonate via Prins reaction between salicylaldehydes and allyl alcohols is realized under mild conditions. A series of compounds containing dioxabenzobicyclo[3.2.1]octane motifs are obtained in moderate to good yields. The current method can efficiently construct the valuable structural motif from easily accessed starting materials, providing a smooth method to build benzobicyclo skeletons.
