Copper condensation

Base-free Knoevenagel condensation catalyzed by copper metal surfaces.

For the first time Knoevenagel condensation has been catalyzed by elemental copper with unexpected activity and excellent isolated yields. Inexpensive, widely available copper powder was used to catalyze the condensation of cyanoacetate and benzaldehyde under mild conditions. To ensure general applicability, a wide variety of different substrates was successfully reacted.

Ugi post-condensation copper-triggered oxidative cascade towards pyrazoles

Pyrazolidinones were prepared in a two-step sequence starting from α-hydrazonocarboxylic acids. After a four-component Ugi coupling, the resulting hydrazone was engaged in a copper triggered [3 + 2] cycloaddition/aerobic oxidation cascade.

Synthesis of 2-C-substituted benzothiazoles via a copper-promoted domino condensation/S-arylation/heterocyclization process.

Two series of extremely useful 2-C-substituted benzothiazoles containing gem-bisphosphonates and aryl-substituted nitriles were synthesized here via a copper-promoted domino condensation/S-arylation/heterocyclization process.
