Abstract

The production of compounds derived from intramolecular photocycloaddition reactions upon Diels–Alder adducts has received considerable attention, but assignment of the NMR spectra of the photoaddition products has proved problematic, rendering structural determination difficult. This paper reports the complete assignments of the proton and carbon NMR spectra of 11, 11‐dimethoxypentacyclo [5.4.0.0^2,6^.0^3,10^.O^5,9^] undecan‐8‐one and the assignment of the spectra of pentacyclo [5.4.0.0^2,6^.0^3,10^.0^5,9^] undecan‐8,11‐dione by analogy.
