General Description

Pentanoic acid, 2-diazo-3-oxo-, ethyl ester is a chemical compound with the molecular formula C7H10N2O3. It is an ethyl ester derivative of pentanoic acid, and its structure contains a diazo group and a keto group. Pentanoic acid, 2-diazo-3-oxo-, ethyl ester is commonly used in organic synthesis as a diazo reagent, particularly in the formation of carbonyl compounds. It is a potentially hazardous and unstable compound that should be handled with caution due to its diazo functional group, which can be explosive under certain conditions. It is important to follow proper safety procedures and handling protocols when working with this chemical.

Rh-Catalyzed Coupling of Acrylic/Benzoic Acids with α-Diazocarbonyl Compounds: An Alternative Route for α-Pyrones and Isocoumarins

A coupling of acrylic acids/benzoic acids with α-diazocarbonyl compounds has been realized by a combined catalytic system of rhodium catalyst and Zn(OAc)2 additive. The presence of Zn(OAc)2 obviously accelerates the C(sp2)

Rhodium(III)-catalyzed chemodivergent annulations between phenyloxazoles and diazos via C–H activation

Acid-controlled, chemodivergent and redox-neutral annulations for the synthesis of isocoumarins and isoquinolinones have been realized via Rh(III)-catalyzed C[sbnd]H activation. Diazo compounds act as a carbene precursor, and coupling occurs in one-pot process, where adipic acid and trimethylacetic acid promote chemodivergent cyclizations.

INHIBITORS OF HUMAN ATGL

The present invention relates to novel inhibitors of adipose triglyceride lipase (ATGL) having an improved inhibitory activity against human ATGL (hATGL) as well as pharmaceutical compositions comprising these inhibitors, and their therapeutic use, particularly in the treatment or prevention of a lipid metabolism disorder, including, e.g., obesity, non-alcoholic fatty liver disease, type 2 diabetes, insulin resistance, glucose intolerance, hypertriglyceridemia, metabolic syndrome, cardiac and skeletal muscle steatosis, congenital generalized lipodystrophy, familial partial lipodystrophy, acquired lipodystrophy syndrome, atherosclerosis, or heart failure.
