1-(Hydroxyiminomethyl)-2-naphthol
The title compound, C(11)H(9)NO(2), was prepared by a condens-ation reaction of 2-hydr-oxy-1-naphthaldehyde with hydroxyl-ammonium chloride in refluxing ethanol. An intra-molecular O-H⋯N hydrogen bond is observed. In the crystal structure, inter-molecular O-H⋯O and C-H⋯O hydrogen-bond inter-actions result in a two-dimensional network.
متن کاملIonic Liquid an Efficient Solvent and Catalyst for Synthesis of 1-aminoalkyl-2-naphthol and Naphthoxazine Derivatives
The aim of doing this research is a one-pot three-component synthesis of 1-aminoalkyl-2- naphthol and naphthoxazine derivatives using the condensation of β-naphthol with various aldehydes and amines in the presence of ionic liquid {[(secondary butyl) methyl] imidazolium bromide} {[sec-bmim]+ Br-, as an efficient catalyst and solvent. The catalyst was prepared according...

متن کامل6-Bromo-2-naphthol–piperazine (2/1)
In the title compound, 2C(10)H(7)BrO·C(4)H(10)N(2), the piperazine (pip) mol-ecule displays a chair conformation and is linked to two mol-ecules of 6-bromo-2-naphthol (bno) via O-H⋯N hydrogen bonds. Weak N-H⋯O hydrogen bonds from pip to bno mol-ecules result in chains propagating in [100]. The chains inter-act via C-H⋯π inter-actions.
متن کاملSYNTHESES, ANTIBACTERIAL AND ANTIFUNGAL ACTIVITIES OF 2-ARYL-4- QUINOLINE- CARBOXAMIDE DERIVATIVES
Reaction of aryl methyl ketone with isatin in the presence of a base afforded 2- arylquinoline-4-carboxylic acid (3). Reaction of diazomethane with compound 3 yielded the ester 4. Compound 5 was prepared from the reaction of N, N'-dialkylethyl (or propyl) arnine with 4. Addition of hydrazine hydrate to compound 4a gave 2- (2- pyridyl) quinoline-4-carboxylic acid hydrazide (6). Reaction of l...
