MANUFACTURING METHOD OF PYRIDINE COMPOUND
-
Paragraph 0023, (2019/12/25)
PROBLEM TO BE SOLVED: To provide a novel manufacturing method of a pyridine compound useful as a precursor of a heterocyclic amide compound useful as a herbicide. SOLUTION: There is provided a manufacturing method of a pyridine compound represented by the formula (1), including a process for reacting a cyano acetic acid ester compound represented by the formula (2) with an enone compound represented by the formula (3) in the presence of a base, then conducting a cyclization process by an acid treatment to generate a compound of the formula (1), and a process for extracting the resulting reaction product in a water layer, and then re-extracting the same in an organic layer. In the formula R1 represents an alkyl group having 1 to 3 carbon atoms, and R2 represents an alkyl group having 1 to 4 carbon atoms. SELECTED DRAWING: None COPYRIGHT: (C)2020,JPOandINPIT

ACYLATED SPIROPIPERIDINE DERIVATIVES AS MELANOCORTIN-4 RECEPTOR MODULATORS
-
Page/Page column 82, (2008/06/13)
Certain novel N-acylated spiropiperidine derivatives are ligands of the human melanocortin receptor(s) and, in particular, are selective ligands of the human melanocortin-4 receptor (MC-4R). They are therefore useful for the treatment, control, or prevention of diseases and disorders responsive to the modulation of MC-4R, such as obesity, diabetes, nicotine addiction, alcoholism, sexual dysfunction, including erectile dysfunction and female sexual dysfunction.
