Noval Route through O–C Bond Formation for the Synthesis of Diastereomeric 2, 4-Disubstituted Pyrano [2, 3-B] Quinolines from 3 Formyl-2-Quinolones via Intramolecular Electrophilic Cyclization

Abstract

One-pot, One-step synthesis of 2, 4-disubstituted pyrano[2,3-b]quinolines from 3-formyl-2-quinolones is described from 3-formyl-2-quinolones via intramolecular electrophilic cyclization.
