Highly pH-Dependent Chemoselective Transfer Hydrogenation of α,β-Unsaturated Aldehydes in Water

The pH-dependent selective Ir-catalyzed hydrogenation of α,β-unsaturated aldehydes was realized in water. Using HCOOH as the hydride donor at low pH, the unsaturated alcohol products were obtained exclusively, while the saturated alcohol products were formed preferentially by employing HCOONa as the hydride donor at high pH. A wide range of functional groups including electron-rich as well as electron-poor substituents on the aryl group of α,β-unsaturated aldehydes can be tolerated, affording the corresponding products in excellent yields with high TOF values. High selectivity and yields were also observed for α,β-unsaturated aldehydes with aliphatic substituents. Our mechanistic investigations indicate that the pH value is critical to the chemoselectivity.

Nucleophilic Amination of Methoxy Arenes Promoted by a Sodium Hydride/Iodide Composite

A method for the nucleophilic amination of methoxy arenes was established by using sodium hydride (NaH) in the presence of lithium iodide (LiI). This method offers an efficient route to benzannulated nitrogen heterocycles. Mechanistic studies showed that the reaction proceeds through an unusual concerted nucleophilic aromatic substitution.

MACROCYCLIC ANTAGONISTS OF THE MOTILIN RECEPTOR FOR TREATMENT OF GASTROINTESTINAL DYSMOTILITY DISORDERS

The present invention provides conformationally-defined macrocyclic compounds that bind to and/or are functional modulators of the motilin receptor including subtypes, isoforms and/or variants thereof. These macrocyclic compounds, at a minimum, possess adequate pharmacological properties to be useful as therapeutics for a range of disease indications. In particular, these compounds are useful for treatment and prevention of disorders characterized by hypermotilinemia and/or gastrointestinal hypermotility, including, but not limited to, diarrhea, cancer treatment-related diarrhea, cancer-induced diarrhea, chemotherapy-induced diarrhea, radiation enteritis, radiation-induced diarrhea, stress-induced diarrhea, chronic diarrhea, AIDS-related diarrhea, C. difficile associated diarrhea, traveller's diarrhea, diarrhea induced by graph versus host disease, other types of diarrhea, dyspepsia, irritable bowel syndrome, chemotherapy-induced nausea and vomiting (emesis) and post-operative nausea and vomiting and functional gastrointestinal disorders. In addition, the compounds possess utility for the treatment of diseases and disorders characterized by poor stomach or intestinal absorption, such as short bowel syndrome, celiac disease and cachexia. The compounds also have use for the treatment of inflammatory diseases and disorders of the gastrointestinal tract, such as inflammatory bowel disease, ulcerative colitis, Crohn's disease and pancreatitis. Accordingly, methods of treating such disorders and pharmaceutical compositions including compounds of the present invention are also provided.

MACROCYCLIC GHRELIN RECEPTOR MODULATORS AND METHODS OF USING THE SAME

The present invention provides novel conformationally-defined macrocyclic compounds that can function as selective modulators of the ghrelin receptor (growth hormone secretagogue receptor, GHS-R1a and subtypes, isoforms and variants thereof). Methods of synthesizing the novel compounds are also described herein. These compounds are useful as agonists of the ghrelin receptor and as medicaments for treatment and prevention of a range of medical conditions including, but not limited to, metabolic and/or endocrine disorders, gastrointestinal disorders, cardiovascular disorders, obesity and obesity-associated disorders, central nervous system disorders, bone disorders, genetic disorders, hyperproliferative disorders and inflammatory disorders.

Kinetic resolution of primary 2-methyl-substituted alcohols via Pseudomonas cepacia lipase-catalysed enantioselective acylation

The enantioselectivities of lipases from Pseudomonas cepacia (PFL, Amano PS, etc.) towards a series of primary 2-methyl-substituted alcohols using vinyl acetate as the acyl donor in transesterifications in organic solvents were studied. In terms of enantioselectivity, the best results were found for 3-aryl-2-methylpropan-1-ols with enantiomeric ratios (E-values) over 100 in most cases, whereas other 3-substituted primary 2-methylpropan-1-ols generally displayed lower enantioselectivities: 3-cycloalkyl-2-methylpropan-1-ols (E ≈ 20) and 2-methylalkan-1-ols (E ≈ 10). Moving the aryl group closer or further away from the chiral centre resulted in low enantioselectivities: 2-arylpropan-1-ols (E 10), 2-methyl-4-(2-thienyl)butan-1-ol (E = 12), 2-methyl-5-(2-thienyl)pentan-1-ol (E = 3.2) and 2-methyl-6-(2-thienyl)hexan-1-ol (E = 3.8).
