One‐Pot Synthesis of Highly Substituted Quinolines in Aqueous Medium and Its Application for the Synthesis of Azalignans

Abstract

A new one‐pot method has been developed for the synthesis of highly substituted quinoline derivatives from α‐amino ketone derivatives/glycine esters/glycine amide and aromatic/aliphatic alkynes/alkenyl esters using molecular I2, K2CO3, and tetra butyl ammonium bromide (TBAB) and sodium dodecyl sulfate (SDS) surfactant combination in water at room temperature within 30–50 min. in moderate to good yields. This protocol has advantages like oxidant free, aqueous medium, simple operation, tolerance of various substrates, and useful for the synthesis of bioactive aza‐lignans.
