Efficient Route

New cyclophane derivatives are synthesized from the reaction of γ-substituted vinamidinium salts with 1,4-phenylenedimethanamine and 2,3,5,6-tetramethylbenzene-1,4-diamine in the presence of acetic acid and acetonitrile as solvent.

The One

An efficient acetic acid catalysed reaction has been developed for the synthesis of 4-aryl substituted pyrrolo[1,2-a]quinoxalines from readily available starting materials. A range of structures have been synthesised in very good to excellent yields. The one-pot reaction proceeds through imine formation, cyclisation followed by air oxidation.
