Synthesis of new guanidium-meldrum acid zwitterionic salts and dynamic NMR study of rotational energy barrier around C-NH bond of guanidine moiety
Aminkhani, Ali
, p. 1791 - 1797 (2014)
Synthesis of the Guanidium-Meldrum acid zwitterionic salts was developed through a three component reaction of 2, 2-dimethyl-1, 3-dioxane-4, 6-dione (Meldrum acid), aromatic aldehydes and N, N, N', N'- Tetramethyl-guanidine in benzen at room temperature.
Sc(OTf)3-catalyzed conjugate allylation of alkylidene meldrum's acids
Dumas, Aaron M.,Fillion, Eric
supporting information; experimental part, p. 1919 - 1922 (2009/09/25)
Alkylidene Meldrum's acids are allylated in a conjugate fashion by allyltin nucleophiles under mild Sc(OTf)3-catalyzed conditions. The addition is functional group tolerant and reactions with nonracemic alkylidenes are highly diastereoselective

Although many methods have been reported for the Knoevenagel condensation of aldehydes and Meldrum's acid, most are not general or use unconventional reagents and conditions. We have found that alkylidene Meldrum's acids form readily in benzene solution u
