The title compound, C(9)H(11)N(3)OS, was prepared by the reaction of 3-methoxy-benzaldehyde and thio-semicarbazide. The benzyl-idene ring and the thio-semicarbazone fragment are slightly twisted, making a dihedral angle of 14.1 (1)°. A weak intra-molecular N-H⋯N hydrogen bond may influence the conformation of the mol-ecule. Inter-molecular N-H⋯S hydrogen bonds build up a three-dimensional network.

An efficient and general copper-catalyzed Goldberg reaction at 90-110 °C between aryl bromides and amides providing the desired products in good to excellent yields has been developed using N,N-dimethylglycine as the ligand. The reaction is tolerant toward a wide range of amides and a variety of functional group substituted aryl bromides. In addition, hindered, unreactive aromatic and aliphatic...

The strong inhibitor effect of aryl iodides on the quasi-homogenous gold-catalyzed oxidation reaction was described. Aryl iodides were adsorbed on the exposed surface of Au clusters, which affected the accessibility of the nanoclusters to the reacting species and acted as strong inhibitors in catalysis.

In the mol-ecule of the title compound, C(12)H(20)N(4)O(2), the dihydro-piperidine ring assumes a half-chair conformation. In the crystal, cllassical N-H⋯O and N-H⋯N inter-molecular hydrogen bonds link mol-ecules into double chains along the a axis.

Simple and efficient procedures for the Pd-catalyzed cross-coupling reaction of aryl chlorides and dimethylamine are described. At room temperature with a strong base, t-BuXPhos is employed as the supporting ligand; at 110 °C with a weak base, XPhos is employed as the supporting ligand. In each of these cases, commercially available solutions constitute the source of the dimethylamine, and rece...

N-Alkenyl ureas and N-alkenyl carbamates, like other N-acyl enamines, are typically nucleophilic at their β-carbon. However, by incorporating an α-aryl substituent, we show that they will also undergo attack at the β-carbon by organolithium nucleophiles, leading to the products of carbolithiation. The carbolithiation of E and Z N-alkenyl ureas is diastereospecific, and N-tert-butoxycarbonyl N-a...

A general rhodium-catalyzed oxidative coupling reaction between internal alkynes and aryl aldimines is described. This process affords 3,4-disubstituted isoquinolines in good yield and high regioselectivity. Preliminary mechanistic studies suggest that the C-N bond formation arises from the reductive elimination of a rhodium(III) species.

BACKGROUND Mitochondrial dysfunction and bioenergetic stress play an important role in the etiology of alcoholic liver disease. Previous studies from our laboratory show that the primary methyl donor S-Adenosylmethionine (SAM) minimizes alcohol-induced disruptions in several mitochondrial functions in the liver. Herein, we expand on these earlier observations to determine whether the beneficial...

An aqueous primary standard is needed for measuring cholesterol by enzymatic procedures. Sodium deoxycholate solubilizes cholesterol in water. Crystalline cholesterol (1.00, 3.00, 4.00, and 5.00 g/L), added to a solution containing 150 g of this compound per liter of a 9 g/L saline solution, was measured by a cholesterol oxidase procedure, with a centrifugal analyzer. The solubilizer did not in...
