This paper discusses the synthesis of privileged structures 4H-benzo[1,4]thiazin-3-one and 1,1-dioxo-1,4-dihydro-2H-1lambda6-benzo[1,4]thiazin-3-one derivatives in a parallel solution-phase manner using 1,5-difluoro-2,4-dinitrobenzene. Each scaffold possesses four diversity points. A cheap and efficient oxidant, urea-hydrogen peroxide (UHP), was applied for the introduction of the

This paper discusses the synthesis of benzo[1,4]oxazin-3-one-based compounds from 1,5-difluoro-2,4-dinitrobenzene (1), including benzo[1,4]oxazin-3-ones (5-11) and five novel benzo[1,4]oxazin-3-one-based tricycles: 6-hydroxy-4H-1-oxa-4,5,8-triazaanthracen-3-one (14), 3,8-dihydro-5-oxa-1,3,8-triazacyclopenta-[b]-naphthalene-7-one (15, 17, 21), 3,8-dihydro-5-oxa-1,2,3,8-tetraazacylopenta[b]-naphthalene-7-one (16, 20), 3,8-dihydro-1H-5-oxa-1,3,8-triazacyclopenta[b]-naphthalene-2,7-dione (18, 22), and 5,8-dihydro-4H-1-oxa-4,5,8-triazaanthracene-3,6,7-trione (19).

The UL9 gene of herpes simplex virus type 1 (HSV-1) encodes an origin binding protein (OBP). It is an ATP-dependent DNA helicase and a sequence-specific DNA-binding protein. The latter function is carried out by the C-terminal domain of OBP (DeltaOBP).
