Synthesis and Elimination Pathways of 1-Methanesulfonyl-1,2-dihydroquinoline Sulfonamides
A series of new Morita–Baylis–Hillman acetates were prepared and reacted with methanesulfonamide (K2CO3, DMF, 23 °C) to produce tertiary dihydroquinoline sulfonamides in high yields.

Nitriles in heterocyclic synthesis: Novel syntheses of benzo[b]pyrans, naphtho[1,2-b]pyrans, naphtho[2,1-b]pyrans, pyrano[3,2-h]quinolines and pyrano[3,2-c]quinolines [PDF]
Benzo[b]pyrans, naphtho[1,2-b]pyrans, naphtho[2,1-b]pyrans, pyrano[3,2-h]quinolines, and pyrano[3,2-c]quinolines were synthesized by the reaction of cinnamonitriles with phenols, naphthols, 8-hydroxyquinoline, and 1-methyl-4-hydroxy-2-quinoline.

Quinoline-2-carbaldehyde [PDF]
The title compound, C(10)H(7)NO, crystallizes with two almost planar mol-ecules (A and B) in the asymmetric unit (r.m.s. deviations = 0.018 and 0.020 Å). In the crystal, the A mol-ecules are linked by weak C-H⋯O inter-actions, thereby generating C(9) [001] chains. The B mol-ecules do not exhibit any directional bonding inter-actions.

Quinoline: A versatile heterocyclic
Quinoline or 1-aza-naphthalene is a weak tertiary base. Quinoline ring has been found to possess antimalarial, anti-bacterial, antifungal, anthelmintic, cardiotonic, anticonvulsant, anti-inflammatory, and analgesic activity. Quinoline not only has a wide range of biological and pharmacological activities but there are several established protocols for ...

Synthetic Approaches of Pyrazolyl Quinolines [PDF]
This review article represents a survey of the synthetic strategies leading to pyrazolyl quinolines. The synthetic methods are divided into two main groups based on the type of starting reagents: 1) From quinoline ring onto a pyrazole scaffold, 2) From

In the title compound, C(9)H(8)N(2)O(2)S, the sulfamoyl NH(2) group is involved in intra-molecular N-H⋯N and inter-molecular N-H⋯O hydrogen bonding. In the crystal, molecules are linked via pairs of N-H⋯O hydrogen bonds, forming inversion dimers, which are further associated through π-π stacking inter-actions between the quinoline benzene rings ...

Crystalline Quinolinate Phosphoribosyltransferase
Abstract Quinolinate phosphoribosyltransferase catalyzes the formation of nicotinic acid mononucleotide, carbon dioxide, and inorganic pyrophosphate from quinolinic acid and 5-phosphoribosyl 1-pyrophosphate. The enzyme has a molecular weight of 165,000 and can be irreversibly dissociated into inactive protein units with a molecular weight of 54,000 ...

Divergent Synthesis of Quinolines: Exploiting the Duality of Free Radicals [PDF]
Herein, we present a green scheme for the divergent synthesis of two polysubstituted quinolines from a singular substrate via exploiting free-radical duality.
