Abstract

A complete NMR analysis with full assignment for ^1^H and ^13^C NMR spectral data for 5‐(acetyloxy)‐3‐hydroxy‐9,10‐dimethoxy‐6‐oxo‐11‐oxatricyclo[6.2.1.0^2,7^]undec‐2‐yl acetate (8) is described. This compound was prepared by rapid hydrogenation of the unstable Diels–Alder adduct obtained from the reaction between 3,4‐dimethoxyfuran (4) and 2,5‐diacetoxy‐1,4‐benzoquinone (5). Full homonuclear hydrogen coupling constants measurements and molecular mechanics calculations were performed for the determination of the relative stereochemistry.
