Complete assignments of 1H and 13C NMR spectral data for 7,7′-dihydroarylnaphthalene lignan lactones

In this article we present a complete 1H and 13C NMR spectral analysis of three 7,7′‐dihydroarylnaphthalene lignan lactones using modern NMR techniques such as COSY, HSQC, HMBC and NOE experiments. Complete assignment and homonuclear hydrogen coupling constant measurements were performed. Copyright © 2009 John Wiley & Sons, Ltd.
