title: An efficient synthesis of pyrido[1,2-a]indoles through aza-Nazarov type cyclization.
abstract: Transition metal free Brønsted acid mediated synthesis of biologically important pyrido[1,2-a]indole scaffolds through aza-Nazarov type cyclization of readily available diaryl(2-pyridyl)methanol using formic acid has been developed. This methodology has been successfully extended to synthesize atropisomers.
