We have developed a high-efficiency and practical Cu-catalyzed cross-coupling to directly construct versatile α-aryl-esters by utilizing readily available aryl bromides (or chlorides) and malonates. These gram-scale approaches occur with turnovers of up to 1560 and are smoothly conducted by the usage of a low catalyst loading, a new available ligand, and a green solvent. A variety of functional groups are tolerated, and the application occurs with α-aryl-esters to access nonsteroidal anti-inflammatory drugs (NSAIDs) on the gram scale.

Paragraph 0197-0198, (2021/05/29)
To provide a novel T-type calcium channel blocker. A compound represented by the following General Formula (I), a tautomer or a stereoisomer of the compound, a pharmaceutically acceptable salt of the compound, or a solvate of the compound, the tautomer, the stereoisomer, or the salt is used as a T-type calcium channel blocker. wherein A represents a phenyl which may have a substituent, a 4-membered to 6-membered heteroaryl ring composed of one to three identical or different heteroatoms selected from an oxygen atom, a sulfur atom, and a nitrogen atom and carbon atoms as ring-constituting atoms, or a heterocondensed ring composed of the heteroaryl ring and either a benzene ring or a 6-membered heteroaryl ring composed of one to two nitrogen atoms and carbon atoms, wherein the heteroaryl ring or the heterocondensed ring may have a substituent and is bonded to a nitrogen atom of the adjacent cyclic amino by means of a carbon atom constituting these rings; B represents a phenyl which may have a substituent, a 5-membered or 6-membered heteroaryl ring composed of one to three identical or different heteroatoms selected from an oxygen atom, a sulfur atom, and a nitrogen atom and carbon atoms as ring-constituting atoms, or a heterocondensed ring composed of the heteroaryl ring and either a benzene ring or a 6-membered heteroaryl ring composed of one to two nitrogen atoms and carbon atoms, wherein the heteroaryl ring or the heterocondensed ring may have a substituent and is bonded to the adjacent cyclopropyl ring by means of a carbon atom constituting these rings; R1 and R2, which may be identical or different, each represent a hydrogen atom, a halogen atom, or the like; R3 represents a hydrogen atom, a halogen atom, or the like; n and m, which may be identical or different, each represent 0 or 1; and p represents 1 or 2.

Over the past 40 years, intramolecular hydroacylation has favored five-membered rings, in preference to four membered rings. Herein, we report a catalyst derived from earth-abundant cobalt that enables preparation of cyclobutanones, with excellent regio-,
Decarboxylative allylation of amino alkanoic acids and esters via dual catalysis
Lang, Simon B.,O'Nele, Kathryn M.,Tunge, Jon A.
