— C 4 ‐ ‐ Photocycloaddition of 5,7‐dimethoxycoumarin (DMC) to thymine (λ≥ 300 nm) was studied in dioxane‐water solution, in aqueous frozen state, and solid film state. The major product was isolated and characterized by physical methods. Elemental analysis data, spectral analyses, and photo‐splitting of the product indicate the product to be a 1:l C 4 ‐ ‐ cycloadduct of DMC and thymine.
