John A. Secrist, Jorge R. Barrio, § Nelson J. Leonard,* and Gregorio Weber abstract: The synthesis of fluorescent derivatives of adeno-sine and cytidine, by reaction with chloroacetaldehyde in aqueous solution at mild pH and temperature, yielding 1, 7V6-ethenoadenosine hydrochloride and 3, 7V4-ethenocytidine hydrochloride, respectively, is here described. Analogous derivatives of 3'-AMP, 5'-AMP, 3', 5'-cyclic AMP, ADP, ATP, and NAD+ were also synthesized. Observation of the spectroscopic properties of the highly fluorescentadenosine derivatives included the emission maximum for 1, 7V6-etheno-adenosine at ca. 415 nm (corrected) in bufferedaqueous solu-tion at pH 7.0, a quantum yield of 0.56, and a fluorescence lifetime of 20 nsec. Variations in fluorescence with respect
