A facile one-pot synthesis of novel steroidal dispiro-indenoquinoxaline pyrrolidines via multicomponent-[3+2]-cycloaddition of azomethine ylides in ionic liquid is described. The structure of cycloadduct is confirmed by IR, H-1 NMR, C-13 NMR, high resolution mass spectroscopy and elemental analysis. (C) 2016 Elsevier Inc. All rights reserved.
