Abstract

A “skeleton-first, oxidation-late” two-step route is reported to synthesize a fused N-oxide (2), featuring a one-pot functionalization strategy introducing nitro and N-oxide moieties. Compound 2 exhibits an exceptionally high density (1.98 g cm⁻³), excellent detonation velocity (9023 m s⁻¹), and low sensitivities (IS = 30 J, FS > 360 N).
