资源简介：
A new method for the construction of tetrahydropyrans derived from readily available 1,2-dioxines
containing a tethered hydroxyl moiety is described. The reaction proceeds via a base-catalyzed
rearrangement of the 1,2-dioxines to either the isomeric cis or trans γ-hydroxy enones followed by
intramolecular oxa-Michael addition of the tethered hydroxyl group.
