چکیده

Aldehydes can be α-alkylated with allenamides by the combined action of an organocatalyst and a gold complex. The reaction requires the simultaneous generation of an enamine and a gold-activated allenamide. Importantly, by using a chiral amine as organocatalyst it is possible to obtain aldehyde products featuring all-carbon quaternary stereocenter at their α-position, with moderate to good levels of enantioselectivity.

Brønsted acid catalyzed α-alkylation of aldehydes with diaryl methyl alcohols.

The catalytic a-alkylation of carbonyl compounds is a common approach in organic synthesis. In recent years, many efforts have been directed towards the activation of ketones and aldehydes by means of enamine catalysis to react with a broad range of electrophiles. In 2004, List reported an elegant intramolecular alkylation of aldehydes with alkyl halides using proline-based amine catalysts. Whi...

The versatile roles of ammonium salt catalysts in enantioselective reduction and alkylation of α,β-unsaturated aldehydes: iminium catalysis, enamine catalysis and acid catalysis.

A novel strategy for highly efficient utilization of chiral ammonium salt catalysts has been described in this paper. Three kinds of catalytic functions including iminium catalysis, enamine catalysis, and acid catalysis of chiral ammonium salt catalysts, have been achieved in the enantioselective reduction and alkylation reaction of α,β-unsaturated aldehydes with alcohols.

Direct, enantioselective α-alkylation of aldehydes using simple olefins.

Although the α-alkylation of ketones has already been established, the analogous reaction using aldehyde substrates has proven surprisingly elusive. Despite the structural similarities between the two classes of compounds, the sensitivity and unique reactivity of the aldehyde functionality has typically required activated substrates or specialized additives. Here, we show that the synergistic m...

In the last years huge efforts have been made to develop new activation modes in order to synthesize complex scaffolds in an enantiopure form. The most common approach has been the development of new catalysts to activate an “unreactive” compound A that will react with a highly reactive compound B to render C. However, recently a new approach pushes the boundaries of organic chemistry: synergis...

Enantioselective a-Alkylation of Aldehydes by Photoredox Organocatalysis: Rapid Access to Pharmacophore Fragments from b- Cyanoaldehydes**

The combination of photoredox catalysis and enamine catalysis has enabled the development of an enantioselective a-cyanoalkylation of aldehydes. This synergistic catalysis protocol allows for the coupling of two highly versatile yet orthogonal functionalities, allowing rapid diversification of the oxonitrile products to a wide array of medicinally relevant derivatives and heterocycles. This met...
