The reaction of 2-amino(alkylamino)-1,4-naphthoquinones with nitrating mixture in concentrated sulfuric acid leads to the formation of 2-amino(alkylamino)-3-nitro-1,4-naphthoquinones.

One-pot synthesis of tetracyclic naphthoxazole derivatives from electron-deficient naphthoquinones and alkynes was achieved via Rh(III)-catalyzed C-H activation and Csp3-H bond cleavage for the first time. This approach proceeds through a tandem cascade process involving substrate tautomerization, C-H activation, oxidative addition, cyclization, and aromatization. In addition, broad substrate scope, simple starting materials, and steric tolerance make this strategy of great practicality.
