2-aminopyridines frompyridine N-oxides via their corresponding N-(2-pyridyl)pyridinium salts has been demonstrated and investigated. The reaction sequence features a highly regioselective conversion of the N-oxide into its pyridinium salt followed by hydrolytic decomposition of the pyridinium moiety to furnish the 2-aminopyridine product. The method is compatible with a wide range of functional groups, is

Provided are a material for an organic electroluminescent element formed of a silicon-containing four-membered ring compound, and an organic electroluminescent element using the material. The material for an organic electroluminescent element is formed of a compound represented by the following formula (1) and is used for, for example,a light-emitting layer containing a phosphorescent light-emitting dopant in an organic electroluminescent element. In the formula, X represents nitrogen or phosphorus, L's each represent an (n+1)-valent aromatic hydrocarbon group or aromatic heterocyclic group, and at least one of the L's represents an aromatic heterocyclic group. A1 to A6 each represent an alkyl group, a cycloalkyl group, an alkenyl group, an alkynyl group, an aromatic hydrocarbon group, an aromatic heterocyclic group, or an amino group, and n represents an integer of 0 to 3.
discover new small molecule diacylglycerol acyltransferase (DGAT)-1 inhibitors, screening of our in-house chemical library was carried out using recombinant human DGAT-1 enzyme. From this library, the lead compound 1a was identified as a new class of DGAT-1 inhibitor. A series of novel N-(substituted heteroaryl)-4-(substituted phenyl)-4-oxobutanamides 2 was designed from 1a, synthesized and evaluated
