‐chromenes and spirochromenes using basic ionic liquid, 2‐hydroxyethylammonium formate as green, stable, and reusable catalyst
2-amino-4H-chromenes and spirochromenes were fabricated in a one-pot three-component synthesis manner from commercially available chemicals including phloroglucinol, malononitrile, and aldehydes/isatines with acceptable and easy efficiencies. This methodology was performed in the presence of 2-hydroxyethylammonium formate as an effective and reusableionicliquidcatalyst. Water was selected as the
