摘要：AbstractSpiropyrrolidine engrafted ferrocene heterocycles were synthesized in excellent yields in a sustainable fashion employing an ionic liquid, 1-butyl-3-methylimidazoliumbromide accelerated one-pot multicomponent cycloaddition strategy. Thein situ1,3-dipole component derived from indenoquinoxalinone and L-phenylalanine that reacts with various substituted ferrocenyl chalcone in [bmim]Br affording spirocycloadduct.
