ChemInform Abstract: From Simple Furans to Complex Nitrogen‐Bearing Aromatic Polycycles by Means of a Flexible and General Reaction Sequence Initiated by Singlet Oxygen.

Abstract

A general one-pot reaction sequence is developed to convert simple furan derivatives into nitrogen-bearing polycyclic heterocycles. Key feature of the process is the generation of an N-acyliminium ion in a novel way and subsequent intramolecular trapping with an amine. -(KALAITZAKIS, D.; MONTAGNON, T.; ANTONATOU, E.; BARDAJI, N.; VASSILIKOGIANNAKIS*, G.; Chem. -Eur.
