In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Synthesis of isoindolo[1,2-a]isoquinoline and isoindolo[2,1-a]quinoline derivatives via trifluoroacetic acid-mediated cascade reactions, published in 2021-07-30, which mentions a compound: 1260795-42-3, Name is Methyl 4-bromo-2-formylbenzoate, Molecular C9H7BrO3, Recommanded Product: 1260795-42-3.
Condensation of Me 2-acylbenzoates with 2-arylethanamines or 2-acylanilines in the presence of trifluoroacetic acid resulted in the formation of isoindolo[1,2-a]isoquinolines or isoindolo[2,1-a]quinolines, resp., in moderate to excellent isolated yields.
《Synthesis of isoindolo[1,2-a]isoquinoline and isoindolo[2,1-a]quinoline derivatives via trifluoroacetic acid-mediated cascade reactions》 provides a strategy for the preparation of materials with excellent comprehensive properties, which is conducive to broaden the application field of this compound(Methyl 4-bromo-2-formylbenzoate)Recommanded Product: 1260795-42-3.
