be an efficient catalyst for the one-potmulti-componentsynthesis of fully substituted new indeno[1,2-b]pyridinesthrough a combination of 1,3-indandione, propiophenone or 2-phenylacetophenone, aromatic aldehydes, and ammonium acetate at room temperature. The same methodology also worked well for the construction of several other 2,3,4,5,6-pentasubstituted pyridines at room temperature. Atom economy
