Abstract Dual catalysis is one of the most powerful strategies for development chemical reactions in organic synthesis. This strategy can be divided into cooperative catalysis, relay and sequential according to actual mode operation communication between catalysts. In recent years, such has been applied a large number studies since it advantages of: 1) increasing reactivity enabling challenging transformations; 2) offering way controlling stereoselectivity asymmetric reactions, which traditional catalytic systems; 3) catalyze stereodivergent synthesis molecules bearing or more stereocenters from same starting materials. Perspective, intends introduce reader EurJOC special collection on Catalysis , aims summarize different categories dual demonstrate their benefits constructing new bonds selective manner. Finally, current challenges trends will also presented.

Aldehydes constitute a main class of organic compounds widely applied in synthesis. As such, catalyst-controlled enantioselective α-functionalization aldehydes has attracted great interest over the years. In this context, α-branched are especially challenging substrates because reactivity and selectivity issues. Firstly, transient trisubstituted enamines enolates resulting upon treatment with an aminocatalyst or base, respectively, would exhibit attenuated reactivity; secondly, mixtures E- Z-configured enamines/enolates may be formed; third, effective face-discrimination on such sp2 carbon intermediates by incoming electrophilic reagent is not trivial. Despite these issues, last 15 years, several catalytic approaches for prostereogenic that proceed useful yields diastereo- enantioselectivity have been uncovered. Developments include both organocatalytic metal-catalyzed as well dual catalysis strategies forging new carbon–carbon carbon–heteroatom (C-O, N, S, F, Cl, Br, …) bond formation at Cα starting aldehyde. review, some key early contributions to field presented, but focus most recent methods, mainly covering literature from year 2014 onward.

Abstract Herein, we report synergistic copper/amine‐catalyzed reactions for directly α‐benzylating carbonyl compounds with arylacetic acids. These represent the first examples of decarboxylative oxidative transition‐metal/enamine catalysis α‐functionalizing compounds. The process features starting‐material availability, good functional group tolerance, mild reaction conditions, and good‐to‐excellent yields. Dibenzylated products were formed in moderate yields under slightly altered some transformed into 1,2,3,4‐tetrahydrocyclopenta[ b ]indole derivatives by acid‐catalyzed intermolecular cyclization indoles. Moreover, biological studies revealed that have anticancer properties may be useful drug‐discovery studies. magnified image
