    • 1H NMR. The protons on C-2 of a dioxaspiro[3.2]hexane appear above 5.0 ppm in oxetane-intact products and shift to below 5.0 ppm in ring-opened products.

    • note
    • Compound 1 was isolated as a mixture of diastereomers (14: 1). The identity of the major diastereomer is not known. Evidence (see ref 6) suggests that diastereoselectivity is largely sterically controlled. It is noteworthy that the diastereomeric ratio is inconsequential for the subsequent transformations of 1 in the applications described in this paper.
