Introduction Multi-component reactions (MCR), are reactions in which three or more starting materials react together to form a target product. In other words, multicomponent reactions are reactions where more than two compounds combine in a sequential manner to obtain highly selective products that remain majority of the atoms of the starting material in the products [1–6]. Pyranopyrazoles are an interesting class of heterocyclic compounds due to their important properties. They have been used as fungicidal , bactericidal , vasodilatory , anticancer , pharmaceutical ingredient, and biodegradable agrochemical  agents. Also, pyrano[2,3-c]pyrazoles have acted as potential insecticidal  and molluscicidal agents [13, 14]. Some catalysts have been used for this transformation, including imidazole , per-6-amino-b-cyclodextrin , phase transfer catalyst (HDBAC) , organocatalyst (MDOs) , D,L-Proline , hexa decyl tri methyl ammonium bromide
