title: Synthesis of diazaphenoxathiin nucleosides from 3-deazauridine and their chemical properties.
abstract: New method for a synthesis of diazaphenoxathiin skeleton from 3-deazauracil derivatives is reported. It became possible to convert 3-deazauridine to 3-deazacytidine via an excellent intermediate "diazaphenoxathiin sulfoxide derivative".
