Abstract
Abstract— Photochemical and γ‐ray‐induced reactions of purines with amines are described. These lead to the appropriate 8‐substituted purines. The photoproducts were obtained in yields of up to 100% by the use of a variety of photosensitizers, including peroxides. A free radical mechanism is proposed for these reactions.Such reactions may be relevant to the problem of the nature of DNA‐protein cross‐links induced by ultraviolet radiation.Keywords
