3-(7-Methoxy-β-carbolin-1-yl)propionic acid monohydrate
In the title compound, C(15)H(14)N(2)O(3)·H(2)O [systematic name: 3-(7-meth-oxy-9H-pyrido[3,4-b]indol-1-yl)propanoic acid monohydrate], the fused rings make dhedral angles of 0.4 (1), 1.1 (2) and 1.4 (2)°. In the crystal, the water mol-ecule is involved in the formation of three independent hydrogen-bonded chains via O-H⋯O and N-H⋯O hydrogen bonds, while the carb-oxy group forms an inter-molecu...
متن کاملNucleophilic β-Carbon Activation of Propionic Acid as a 3-Carbon Synthon by Carbene Organocatalysis.
Direct β-carbon activation of propionic acid (C2H5CO2H) by carbene organocatalysis has been developed. This activation affords the smallest azolium homoenolate intermediate (without any substituent) as a 3-carbon nucleophile for enantioselective reactions. Propionic acid is an excellent raw material because it is cheap, stable, and safe. This approach provides a much better solution to azolium ...
متن کاملSynthesis and biological assessment of 2-hydroxyiminoethanones as anti-inflammatory and β-amyloid aggregation inhibitors
Alzheimer’s disease (AD) is a neuroinflammatory based pathologic state in which β-amyloid aggregates are a major devastating agents. In this study, a series of 2-hydroxyiminoethanones were synthesized and evaluated as anti-inflammatory in carrageenan and formalin tests and inhibitors of β-amyloid aggregation. Compounds 1-10b were synthesized through a two-step reaction. Results: Compounds 1-5b ...

متن کامل3-[3-(2-Fluorobenzoyl)thioureido]propionic acid
In the title compound, C10H11FN3O3S, the 2-fluoro-benzoyl and proponic acid groups maintain a trans-cis conformation with respect to the thiono C=S bond across their C-N bonds. The propionic acid group adopts an anti conformation about the C-C bond, with an N-C-C-C torsion angle of 173.8 (2)°. The amino groups are involved in the formation of intra-molecular N-H⋯O and N-H⋯F hydrogen bonds. In t...
