A method for producing a compound having a deuterated aromatic ring or heterocyclic ring according to the invention includes heating a compound having an aromatic ring or heterocyclic ring in the presence of heavy water, a transition metal and a metal which generates deuterium. As the metal which generates deuterium, at least one metal selected from the group consisting of aluminum, magnesium, zinc, iron, lead and tin is preferred. As the transition metal, at least one metal selected from the group consisting of platinum, palladium, ruthenium and rhodium is preferred. The heating is preferably carried out by microwave irradiation.

The invention provides tricyclic compounds and their use in treating liver disorders, such as non-alcoholic steatohepatitis and related disorders (e.g., fibrosis). The compounds are contemplated to have activity against methionyl aminopeptidase 2.
Malonicacid derivatives undergo unusually mild decarboxylation when treated with N,N′-carbonyldiimidazole (CDI) at room temperature to generate the carbonyl imidazole moiety in high yield, which can be reacted further with a variety of nucleophiles in an efficient one-pot process.

The copper-catalyzed H-F insertion into α-diazocarbonyl compounds is described using potassium fluoride (KF) and hexafluoroisopropanol. Access to complex α-fluorocarbonyl derivatives is achieved under mild conditions, and the method is readily adapted to radiofluorination with [(18)F]KF. This late-stage strategy provides an attractive route to (18)F-labeled biomolecules.

A reaction for H–F bond insertion into α-diazo carbonylcompounds is reported. The protocol describes a simple reaction setup employing commercially available HF·pyr (Olah reagent) as the fluorine source. The method is rapid and practical, and allows access to a broad range of α-fluorinated carbonylcompounds in generally good yields.
