The present invention provides a compound of Formula (I) and the pharmaceutically acceptable salts, esters, and prodrugs thereof, which are PRMT5 inhibitors. Also provided are methods of making compounds of Formula I, pharmaceutical compositions comprising compounds of Formula I, and methods of using these compounds to treat cancer, sickle cell, and hereditary persistence of foetal hemoglobin (HPFH) mutations.
A process for fluorination of aromatic compounds employing iodonium ylides and applicable to radiofluorination using 18F is described. Processes, intermediates, reagents and radiolabelled compounds are described.
Disclosed is a hydrocarboxylation process for the production of carboxylic acid from olefins wherein an olefin, water, a Group VIII metal hydrocarboxylation catalyst, an onium salt compound are combined in a reaction zone and contacted with carbon monoxide under hydrocarboxylation conditions of pressure and temperature The process does not require or utilize the addition of a hydrogen halide or an alkyl halide exogenous or extraneous to the hydrocarboxylation process.
Corrosion of steel in acidic solution is inhibited using a mixture of a compound in which a plurality of heterocyclic aromatic groups with a quaternary nitrogen atom are connected together, such as by a linking group which may be covalently attached to the quaternary nitrogen atoms of the aromatic heterocyclic rings, and a polarizable adsorption-intensifying anion.
Disclosed is a carbonylation process for the production of carboxylic acids, carboxylic acid esters and/or carboxylic acid anhydrides wherein a carbonylation feedstock compound selected from one or more organic oxygenates such as alcohols, ethers, and esters is contacted with carbon monoxide in the presence of a carbonylation catalyst and one or more onium compounds. The carbonylation process differs from known carbonylation processes in that a halide compound such as a hydrogen halide, typically hydrogen iodide, and/or alkyl halide, typically methyl iodide, extraneous or exogenous to the carbonylation process is not fed or supplied separately to the process.
