Abstract
Abstract Photoirradiation of 1-{9-[(2-acetoxyethoxy)methyl]-9 H -purin-6-yl}-pyridinium chloride ( 1b ) in aqueous solution leads to two photoproducts, namely 1-{5-formamido-6-[(2-acetoxyethoxy)methylamino]pyrimidin-4-yl}pyridinium chloride ( 2b ) and 1-(6-(acetoxymethyl)-5,5a,6,8-tetrahydrooxazolo[4,3- e ]purin-4-yl)pyridinium chloride ( 6 ), which constitutes a new heterocyclic system. Further, photosensitized irradiation of 2b gave the desired acyclic nucleoside analog of the highly fluorescent luminarosine 3b .
