Synthesis of chromeno[2鈥?3鈥?4,5]imidazo[2,1-a]isoquinolines via a novel domino reaction of isoquinoline-derived immonium salts. Scope and limitations
摘要
A one-pot protocol towards chromeno[2鈥?2鈥?4,5]imidazo[2,1-a]isoquinoline derivatives via a domino reaction of isoquinoline-derived immonium salts and 伪-hydroxy aromatic aldehydes is elaborated. The scope and limitations of this reaction is discussed.
