Solar-driven carbonylation with CO2 replacing toxic CO as a C1 source is of considerable interest; however it remains a great challenge due to the inert CO2 molecule. Herein, we integrate cobalt single-site and ultrafine CuPd nanocluster catalysts into a

Palladium-Catalyzed Asymmetric Dearomative Carbonylation of Indoles.
Organic Letters, 2022Herein, we disclose a strategy for the asymmetric dearomatization of N-arylacyl indoles via a palladium-catalyzed tandem Heck/carbonylation, leading to an array of indoline-3-carboxylates bearing vicinal C2-aza-quaternary and C3 tertiary stereocenters in

Carbonyl reductase (secondary-alcohol:NADP(+) oxidoreductase, EC 1.1. 1.184) belongs to the family of short chain dehydrogenases/reductases (SDR). Carbonyl reductases (CBRs) are NADPH-dependent, mostly monomeric, cytosolic enzymes with broad substrate specificity for many endogenous and xenobiotic carbonyl compounds.

1,4-Carbonyl-carbonyl interactions
Experientia, 1960Es wird gezeigt, dass die IR-Spektren gewisser 1,4-Diketone und 1,4-Ketoester abnorm hohe Carbonylfrequenzen aufweisen, was auf das Vorhandensein eines intramolekularen Feldeffekts zwischen den beiden Carbonylgruppen in diesen Verbindungen hindeutet. Die ungewohnlichen Stabilitatsverhaltnisse an C-20 der 16,22-Dicarbonyl-Steroide sind vermutlich auf ...

Synthesis of α,β-unsaturated carbonyl compounds by carbonylation reactions.
Chemical Society Reviews, 2020α,β-Unsaturated carbonyl compounds are key building blocks in organic chemistry. Their catalytic synthesis has received significant attention during the past decades. Among the known methodologies, carbonylation reactions represent an atom-efficient tool
