A series of 2-oxopiperazine derivatives were designed from the pyrrolopiperazinone cell-based screening hit 4 as a dengue virus inhibitor. Systematic investigation of the structure-activity relationship (SAR) around the piperazinone ring led to the identification of compound (S)-29, which exhibited potent anti-dengue activity in the cell-based assay across all four dengue serotypes with EC50 < 0.1 mu M. Cross resistant analysis confirmed that the virus NS4B protein remained the target of the new oxopiperazine analogs obtained via scaffold morphing from the HTS hit 4. (C) 2017 Elsevier Ltd.

Rhodium(II) perfluorobutyrate-mediated decomposition of vinyl azides provides a new, mild entry into Rh-2(II) nitrenoid chemistry. This methodology allows rapid access to a variety of complex, functionalized N-heterocycles in two steps from commercially available starting materials.
