Abstract
The high-resolution proton magnetic resonance spectra of curzerenone observed in 20 mole percent solution in carbon tetrachloride and deuterochloroform were analyzed with the aid of the computation and the double resonance experiments. The relative sign of the coupling constants was determined by the spin-tickling method, and the accurate values of parameters were obtained. It was confirmed the presence of the long-range spin coupling 5JHH via the ether linkage in the fused furan ring, and the values of nuclear magnetic resonance parameters were shown to be reasonable for the predicted structure.
