The title compound, C(25)H(38)O(5), was formed by the reaction of dimethyl 2-butyl-malonate and 2,6-di-tert-butyl-4-[(dimethyl-amino)meth-yl]phenol. In the crystal structure, mol-ecules are linked by inter-molecular O-H⋯O hydrogen bonds into chains along [010].

The solubilities of amino acids, diglycine, and triglycine have been measured in water and aqueous ethanol as well as dioxane solutions. Free energies of transfer of amino acid side chains and backbone peptide units from water to ethanol and dioxane solutions have been calculated from these data. The results show the similarity between the ‘effects of ethanol and dioxane on the stability of tho...

In the title racemic compound, C14H15NO, the hy-droxy and amino groups form a bent tweezer-like motif towards the phenyl groups. In the crystal, enanti-omers aggregate with each other and are linked by O-H⋯N hydrogen bonds, forming chiral 21-helical columnar structures from C(5) chains along the b-axis direction. Left- and right-handed 21 helices are formed from (1S,2R)-2-amino-1,2-di-phenyl-et...

In the title compound, C(7)H(11)N(2) (+)·C(7)H(7)O(3)S(-), the cation is protonated at the N atom of the heterocyclic ring. The dimethyl-amino group lies close to the pyridinium ring plane with a dihedral angle between the pyridinium and the dimethyl-amine CNC planes of 3.82 (17)°. The N-C bond linking the dimethyl-amino substituent to the pyridinium ring is characteristically short [1.3360 (19...

Objective: Ethanol abuse exacerbates copper (Cu) and zinc (Zn) deficiencies resulting in metabolic alterations that frequently lead to increased ethanol intake. This preliminary study examined the effect of Cu and Zn amino acid chelate (AAC) supplementation on ethanol intake in ethanol-dependent rats compared to non-supplemented ethanoldependent rats. Methods: After creating ethanol dependency ...

In the title compound, [Ho(C(6)H(12)Cl(3)N(3)O(2)P)(3)(C(18)H(15)OP)], the Ho(III) ion is surrounded by six O atoms from the three bidentate N-[bis-(dimethyl-amino)phosphino-yl]-2,2,2-trichloro-acetamido ligands (L(-)) and by one O atom from the triphenyl-phosphine oxide ligand, with the formation of a distorted monocapped octa-hedron. In one ligand L(-), the trichloro-methyl group is rotationa...

In the title compound, C(31)H(29)NO(5), the methyl carboxyl-ate and dimethyl-amino groups on the naphtho-pyran group are almost coplanar with the naphtho-pyran ring system [r.m.s. deviations = 0.08 (2) and 0.161 (2) Å, respectively]. The dihedral angle between the methyl carboxyl-ate and dimethyl-amino groups is 4.9 (1)°. The pyran ring has an envelope conformation with the quaternary C atom ou...

In the title compound, (C(7)H(11)N(2))(2)[ZnCl(4)], [ZnCl(4)](2-) anions and 4-(dimethyl-amino)-pyridinium cations are held together by various inter-molecular inter-actions including Coulombic attraction, hydrogen bonding and π-π stacking inter-actions. Three Cl atoms of the [ZnCl(4)](2-) tetra-hedron act as acceptors in N-H⋯Cl hydrogen bonds. The hydrogen bonds, both of which are bifurcated, ...

Reaction of the tricarbon-yl{η(5)-[2-(dimethyl-amino)eth-yl]cyclo-penta-dien-yl}molybdenum anion and dichlorido-diphenyl-stannane affords the title compound, [MoSn(C(6)H(5))(2)Cl(C(9)H(14)N)(CO)(3)], which exhibits a four-legged piano-stool geometry with chlorido-diphenyl-stannyl ligands unperturbed by the pendant 2-(dimethyl-amino)ethyl groups. The Mo-Sn bond length [2.7584 (5) Å] and the dist...
