A series of pyrazolo[3,4-b]quinolines have been synthesized using one-pot water mediated synthetic route under microwave irradiation involving the condensation of 2-chloroquinoline-3-carbaldehydes with semicarbazide or 2,4-dinitrophenyl hydrazine. The compounds were evaluated for their anti-inflammatory, analgesic, ulcerogenic and lipid peroxidation actions. The pharmacological evaluation showe...
Reaction of 4-oxo-3,4-dihydroquinazoline-2-carbaldehyde with hydroxylamine hydrochloride (1.1 equiv) in the presence K2CO3 (1 gave (E)-4-oxo-3,4-dihydroquinazoline-2-carbaldehyde oxime (8) 58% yield. The compound was fully characterized and conformation supported by single crystal x-ray diffractometry.
In the title compound, C(16)H(13)NO(3)S, the sulfonyl-bound phenyl ring forms a dihedral angle of 84.17 (6)° with the indole ring system. An intra-molecular C-H⋯O hydrogen bond generates an S(6) ring motif. The crystal structure exhibits weak inter-molecular C-H⋯O hydrogen bonds and π-π inter-actions between the five- and six-membered rings of the indole group [centroid-centroid distance = 3.68...
6-Hydroxy-2-oxo-2H-chromene-4-carbaldehyde (2), 6-chloro-2-oxo-2H-chromene-4-carbaldehyde (3) and 6-hydrazinyl-4-methyl-2H-chromen-2-one (5) were prepared as single-pharmacophore motif key intermediates. Compounds 2, 3 and 5 were incorporated in a series of multicomponent reactions (MCRs), under microwave assistance as well as conventional chemical synthesis processes, to afford a series of thr...
