CuCl catalyzed green and efficient one-pot synthesis of aminoindolizine frameworks via three-component reactions of aldehydes, secondary amines, and terminal alkynes in PEG

An ecofriendly one-pot synthesis of aminoindolizines or the corresponding analogs via CuCl catalyzed three component coupling of aldehydes, secondary amines, and terminal alkynes in PEG has been described.
