Halogenation of 6-O-cyclouracil nucleosides.
Bromination or iodination at the 5-position of 6-O-cyclo-uracil nucleosides was effected in a fairly good yield. Besides monohalogenated nucleosides, there were prepared novel dibromo compounds, which were assigned the structure, 5,5-di-bromo-6,6-di-O-cyclouracil nucleosides (VI, VIII).
