Transition metal and hydrogen bond donor hybrids: Catalysts for the activation of alkylidene malonates
Nickerson, David M.,Mattson, Anita E.
, p. 8310 - 8314 (2012)
Palladium ureaka! Urea palladacycles are introduced to activate alkylidene malonates for nucleophilic attack. The strategic incorporation of palladium on a urea scaffold give rise to urea catalysts with enhanced reactivity when compared to conventional ur
Indium(III)-catalyzed knoevenagel condensation of aldehydes and activated methylenes using acetic anhydride as a promoter

The combination of a catalytic amount of InCl3 and acetic anhydride remarkably promotes the Knoevenagel condensation of a variety of aldehydes and activated methylene compounds. This catalytic system accommodates aromatic aldehydes containing a variety of electron-donating and -withdrawing groups, heteroaromatic aldehydes, conjugate aldehydes, and aliphatic aldehydes. Central to successfully driving the condensation series is the formation of a geminal diacetate intermediate, which was generated in situ from an aldehyde and an acid anhydride with the assistance of an indium catalyst.
Synthesis of aminocyclobutanes by iron-catalyzed [2+2] cycloaddition
De-Nanteuil, Florian,Waser, Jerome
supporting information, p. 9009 - 9013 (2013/09/02)
Fab Four: An iron-catalyzed [2+2] cycloaddition furnishes aminocyclobutanes with a broad range of substituents in excellent yields and diastereoselectivities. The products can be obtained on a gram scale and can be further converted to β-peptide derivatives in a few steps. Furthermore, a [4+2] cycloaddition between an aminocyclobutane and an olefin leads to the corresponding cyclohexylamines. Copyright
Ytterbium-catalyzed conjugate allylation of alkylidene malonates
Fallan, Charlene,Quigley, Paul F.,Lam, Hon Wai
experimental part, p. 4112 - 4118 (2011/06/25)
Alkylidene malonates undergo efficient conjugate allylation upon treatment with allylstannanes or allylsilanes under the action of ytterbium catalysis.
A straightforward method for the synthesis of alkylidene and arylidene malonates through proline-catalyzed Knoevenagel condensation
Cardillo, Giuliana,Fabbroni, Serena,Gentilucci, Luca,Gianotti, Massimo,Tolomeklli, Alessandra
, p. 1587 - 1594 (2007/10/03)
A straightforward method for the synthesis of alkylidene/arylidene malonates and arylidene cyanoacetates, utilizing proline as an alternative to traditional catalysts is presented. A large number of unsaturated esters was obtained from the Knoevenagel reaction under very mild conditions and utilizing cheap reagents.
