Colloque
Evidence is provided that the photodimers of o-hydroxy- and o-methoxy cinnamic acids and o-methoxy-trans-cinnamic acids are derivatives of truxillic acid. The dilactone derived from the o-hydroxy derivative is a dimer of coumarin, not identical with the dimer obtained by irradiation of coumarin. The relationship of these compounds will be discussed.
Colloque
Evidence is provided that the photodimers of o-hydroxy- and o-methoxy trans-cinnamic acids are derivatives of α-truxillic acid. The dilactone derived from the o-hydroxy derivative is a dimer of coumarin, not identical with the dimer obtained by irradiation of coumarin. The relationship of these compounds will be discussed.
