Ly. Hsu et al., SYNTHESIS AND ANTIVIRAL EVALUATION OF 3-HYDROXY-METHYLPYRIMIDO[1,6-C][1,3]OXAZEPIN DERIVATIVES, Heterocycles, 48(10), 1998, pp. 2163-2172
A number of pyrimido[1,6-c][1,3]oxazepin derivatives, the anti glycosi
dic constrained acyclic analogs of uridine and cytidine have been prep
ared. Compounds synthesized were evaluated for activity against herpes
simplex virus type 1 (HSV-1) and human cytomegalovirus (HCMV). All of
these compounds were inactive.
