Synthesis of nitroacridinones from 2,1-benzisoxazole derivatives
摘要:
Reaction of 3-aryl-2,1-benzisoxazoles with concentrated nitric acid in chloroform in one stage led to their conversion into acridinone nitro derivatives.

A metal-free synthesis of anthranils from ortho-carbonyl anilines using PhIO as a sole reagent under ambient conditions is described. No external additives are required, the reaction has broad substrate scope and delivers anthranils in excellent yields via oxidative heterocyclization.
We report a novel and practical one-pot Rh(III)-catalyzed strategy to construct benzimidazo[1,2-a]quinolines from readily available imidamides and anthranils. The cascade reaction proceeds via a C-H amination-cyclization-cyclization process in ionic liquid without any additives and possesses simple operation, moderate-to-high yield, and broad substrate scope features, which will provide the reference
