Abstract

To exploit azide chemistry in the nucleoside field, protected 5-bromopyrimidine nucleosides were synthesized as substrates for the reaction of azide ion. These include 2', 3'-0- isopropylidene-5'-O-benzoyl- and-5'-O-tosyl-5-bromouridine (2a and 2b), 2', 3'-0-anisylidene- 5'-O-benzoyl-5-bromouridine (2c), and 2', 3'-0-isopropylidene-5'-0-mesyl-5-bromocytidine (1 1). 2a, b with sodium azide yielded the same compound, 9, 5'-cyclo-3-(2', 3'-O-isopro- ...
