Abstract

Photoreaction of 8-methoxypsoralen (8-MOP) with thymine (${\ge}$ 300 nm) was carried out in the dioxane-water frozen state. One major and two minor monoaddition products between 8-MOP and thymine were isolated by various chromatographic methods. Major monoadduct was characterized to be a C4 cycloaddition product formed between 5,6-double bond of thymine and 3,4-double bond of 8-MOP with cis-anti stereochemistry. Two minor adducts were proved to be stereoisomers of this major adduct.
