RNA Photolabeling Mechanistic Studies: X-ray Crystal Structure of the Photoproduct Formed between 4-Thiothymidine and Adenosine upon Near UV Irradiation
Photochemistry of 4-Thiothymine Derivatives in the Presence of <i>N</i>-9-Substituted-Adenine Derivatives: Formation of <i>N</i>-6-Formamidopyrimidines
after irradiation of a mixture of 1a and 2a (J. Am. Chem. Soc. 1996, 118, 8142-8143). These new observations demonstrate that the replacement of one or both nucleoside sugar residues by a carboxymethyl group does not affect the regioselective course of the photochemical reaction. The thermal decomposition of 3a that resulted from irradiation of 1a in the presence of 2a, was examined along with its behavior
