    摘要: Novel N-sulfinyl-2-carboxyaziridine compounds and novel N-hydrogen-2-hydroxymethylaziridine compounds are provided. The asymmetric synthesis of N-sulfinylaziridines is readily accomplished in high diastereomeric purity and good yield by the Darzens-type reaction of the metal enolate of an .alpha.-haloester and an enantiopure sulfinimine. Ring-opening of these aziridines affords .alpha.-amino acids and the otherwise difficult to prepare syn-.beta.-hydroxy-.alpha.-amino acids, both key structural units found in many bioactive materials. The N-sulfinyl radical may be selectively removed from the novel aziridine compounds by treatment with acid or base. Alternatively, the N-sulfinyl radical may be oxidized to provide the corresponding N-sulfonyl-aziridine, or reduced to form the corresponding 1H-2-hydroxymethylaziridine, either of which may subsequently be ring-opened to provide precursors to bioactive compounds.

    摘要: The invention provides novel cocaine analogs. The invention also provides a method of preparing cocaine analogs with control over the substituents installed at the C-1, C-2, C-3, C-4 and N-8 positions of the tropane bicyclic scaffold. The invention further provides methods of providing anesthesia, blocking reuptake of a monoamine neurotransmitter, and treating depression, by administering to a subject in need of such treatment a pharmaceutical composition comprising a compound of the invention.

    摘要: Methods of producing N-phenyl amines comprise reacting a phenyl-containing isocyanate with HR, and a boron complexing agent in an aprotic solvent, wherein R, is --OH or --COOH (i.e., water or formic acid), neutralizing the resulting N-aryl amide to N-aryl amine and recovering the N-aryl amine.

    摘要: Methods of producing N-aryl amides comprise reacting an aromatic isocyanate compound with substantially anhydrous carboxylic acid and recovering the resulting N-aryl amide. Additionally, or alternatively, methods of forming N-aryl amides comprise reacting an aromatic isocyanate compound with substantially anhydrous carboxylic acid in the presence of an anhydrous hydrogen halide or hydrolytically unstable halide compound and recovering the resulting N-aryl amide. These reactions may occur in the presence of an aprotic solvent.
