abstract = {Recent work has emphasised the importance of D-ribose amino-oxazoline 1 in the synthesis of cytidine ribonucleosides under potentially prebiotic conditions. Upon treatment with cyanoacetylene, 1 is transformed into $\alpha$-D-cytidine ($\alpha$-2), and if an efficient means of anomerising this nucleoside or a derivative thereof were to be found, then the synthesis of one of the key $\beta$-D-nucleosides required to make RNA would be realised. Photoanomerisation of $\alpha$-2 has previously been described, but the yield was extremely low. Therefore, the present study was initiated to determine whether this low yield was the result of a low conversion or competing reaction pathways. {\textcopyright} 2007 Wiley-VCH Verlag GmbH {\&} Co.
