“…Based on our results and those reported in literatures [26,30,[38][39][40], we proposed a mechanism for the one-pot synthesis of polyfunctionalized 4H-pyrans from the condensation of aldehydes, malononitrile and an active methylene compound (Scheme 2). The surface O 2-ions of the solid superbase act as active basic sites to abstract H ?…”

“…The reaction can occur via the initial formation of the intermediate acrylonitrile derivative A followed by its nucleophilic attack of the anion of the acetoacetanilide derivatives to produce the intermediate B. The final products D were formed via the initial cyclization and subsequent tautomerization of the cyclic intermediate C. 22) To survey the scope of this reaction for the synthesis of 4H-pyran and 1,4-dihydropyridine derivatives, different catalyst was used. Thus, the multicomponent reaction of acetoacetani-lide 1a or b with either 2a, b, c or d and 3 in absolute ethanol containing a catalytic amount of ammoniumacetate gave the 1,4-dihydropyridine derivatives 5a-g, respectively (Chart 3).…”

“…In addition, the title compound and its derivatives have been used as potential precursors to prepare 5,7-diazaspiro-[2,5]octane (Elinson et al, 2010), 2-amino-4H-chromene-3-carbonitrile (Ding et al, 2010) and 4H-pyran derivatives (Ye et al, 2010).…”
