Abstract
In contrast to photoreactions of 5-fluoro-l,3-dimethyluracil (5-FDMU) with various naphthalenes including 2-methoxy-naphthalenes that proceeds in a manner to give ethenoquinazolines through 1,4-cycloaddition, UV-irradiation of a mixture of 5-FDMU and naphthalenes with a methoxy group at C-1 gave rise to the formation of novel cycloadducts, methyl 2-[(1E)-3-(5-fluoro-1,3-dimethyl-2-oxo-1,3-dihydropyrimidin-4-ylidene)-prop-l-enyl]benzoates, derived from the novel aromatic Paterno-Buchi type cycloaddition, followed by a concomitant disruption of the initially formed oxetane moiety.
