The reaction mechanism of the Biginelli chemical reaction is a serial of bimolecular reactions leading to the desired dihydropyrimidinone. Accordant to a chemical mechanism proposed by Angelic in 1973 the aldol condensation of ethylacetoacetate 1 and the aryl AldehydeAn aldehyde is letter a compound containing letter a functional group with the structure −CHO, consisting of A carbonyl center with the carbon molecule also bonded to hydrogen and to an R grouping, which is some generic alkyl surgery side chain. The group—without R—is the aldehyde group, as wel known as the formyl group. Aldehydes ar… is the rate-limiting step in the lead to the carbenium ion 2.Organic Chemical science Portal: RSC ontology ID:
