Sajadikhah Keywords N-heterocycle  Dihydropyrrol-2-one  Piperidine  Multi-component reaction  EDDF  Reusable catalyst Introduction Development of novel methodologies that reduce pollution in chemical synthesis has received considerable attention due to increasing environmental concerns. In this context, one active area is the use of an eco-friendly recyclable catalyst instead of conventional, toxic, and polluting Bronsted acid catalyst [1, 2]. Ethylenedi- ammonium diformate (EDDF) is a salt (m.p. 132 C), and recently it was used as a homogeneous catalyst for the synthesis of 4H-pyrans [3], 3-indolochromenes, and 3-indoloxanthenes [4]. Some advantages of EDDF are reusability, low cost, operational simplicity, ease of preparation, and handling. Among the several aspects of green chemistry, the replacement of volatile organic solvents with green solvents such as water and ethanol http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Research on Chemical Intermediates Springer Journals
