Abstract :
UV-irradiation of a solution of 5-fluoro-1,3-dimethyluracil (5-FDMU) in aprotic media effected a stereoselective 1,4-cycloaddition reaction to give a barrelene derivative in high yield. In direct contrast, irradiation of a solution of 5-FDMU and naphthalene in a protic medium afforded 5-(1-naphthyl)uracil as the major product.
