Abstract

A library of 1,2,3,7‐tetrasubstituted indolizines has been synthesized using poly(ethylene glycol) (PEG) as soluble polymer support. The PEG‐bound pyridinium salts reacted with alkenes or alkynes in the presence of Et~3~N via 1,3‐dipolar cycloaddition to give PEG‐bound indolizine derivatives, which were cleaved by 1 % KCN/MeOH to afford 1,2,3,7‐tetrasubstituted indolizines in good to excellent yields.

A 4-alkylthio-substituted aniline anchored to a modified poly(ethylene glycol) of M w = 5000 was selected as a convenient starting material for the liquid-phase synthesis of various imines. Some of these imines were employed in a three-component synthesis of 1,2,3,4-tetrahydroquinolines, carried out
