Synthesis of the novel bicyclic oxepinopyrimidine and fluorinated pyrrolidinopyrimidines

The new 5, 6-disubstituted pyrimidine nucleoside analogues (5-8) were synthesized by addition of the C-6 lithiated pyrimidine derivative to oxirane as key reaction step. The bicyclic tetrahydrooxepinopyrimidine (9) and fluorinated pyrrolidinopyrimidines (12 and 15) were obtained by intramolecular linkage of acyclic chain to the CH2-5 and N-1 of the pyrimidine ring. The structure of compound (9) containing pyrimidine and tetrahydrooxepine skeleton was determined unequivocally by its X-Ray crystal structure analysis.
