Photohydrates of cytidine and cytidylic acids have been definitively characterized to be isomeric 6-hydroxy-5,6-dihydrocytosine derivatives. It has also been demonstrated by nuclear magnetic resonance spectroscopy that the stereochemistry of photohydration is random, the C/sub 5/-H trans to the C/sub 6/-OH undergoes a rapid selective exchange in the presence of proton acids, and the dehydration of photohydrates is a trans-elimination. The mechanism of these processes is discussed.
