N-[(2-Hydroxy-1-naphthyl)(3-nitrophenyl)methyl]acetamide

Synthesis of 1-Hydroxy-2-(Prop-2'-Enyl) 9-Antrone

An efficient synthesis of the 1-hydroxy-2-(prop-2'-enyl)9-anthrone is described. Selective nitration of anthraquinone, reduction to the corresponding amine, diazotization and treatment by sulfuric acid solution afforded the 1-hydroxy-9,10-anthraquinone in good yield as the key intermediate. Reaction with allyl bromide/K2CO3 and subsequent selective reduction accompanie...

(E)-N′-[(2-Hydroxy-1-naphthyl)methyl­ene]benzohydrazide monohydrate

In the title compound, C(18)H(14)N(2)O(2)·H(2)O, the dihedral angle between the benzene ring and the naphthalene system is 5.18 (10)°. Intra-molecular N-H⋯O hydrogen bonds influence the molecular conformation. In the crystal, inter-molecular N-H⋯O and O-H⋯O hydrogen bonds are observed as well as π-π inter-actions between the phenyl ring and the substituted ring of the naphthalene [centroid-cent...

N-Acetyl-2-hydroxy-N′-[methoxy(1-methylindol-2-yl)methyl]benzohydrazide

In the crystal structure of the title Schiff-base, C(20)H(21)N(3)O(4), the amino group forms an N-H⋯O hydrogen bond to the acetyl group of an adjacent mol-ecule, forming a zigzag chain. The 2-hydr-oxy group is inter-nally hydrogen bonded to the amido group though an O-H⋯O hydrogen bond.

Crystal structure of 2-hydroxy-N-(2-hydroxyethyl)-N-{2-hydroxy-3-[(E)-N-hydroxyethanimidoyl]-5-methylbenzyl}ethanaminium acetate monohydrate

The structure of the title hydrated mol-ecular salt, C14H23N2O4 (+)·C2H3O2 (-)·H2O, was determined as part of a wider study on the use of the mol-ecule as a polydentate ligand in the synthesis of Mn(III) clusters with magnetic properties. The cation features intra-molecular O-H⋯N and N-H⋯O hydrogen-bond inter-actions. The crystal structure features a range of inter-molecular hydrogen-bonding in...
