N2 - Lucidene (1), a bis(benzopyranyl) sesquiterpene was isolated from the rootbark of Uvaria lucida ssp. lucida, and its structure was determined by spectroscopic methods and single-crystal X-ray crystallography. It is optically inactive and crystallizes in enantiomeric pairs. High-resolution 1H NMR (400 and 600 MHz) spectroscopy allowed the assignment of all protons and indicated the existence of relatively slowly interconverting conformations. The three known dihydrochalcones, uvaretin, diuvaretin, and chamuvaretin, as well as benzyl benzoate were isolated from the same plant as well.
