چکیده

Treatment of dialkylbenzylsilane (1) with trityl tetrakis(pentafluorophenyl)borate (TPFPB) in the presence of terminal or internal alkynes (3) and 2,6-di-tert-butyl-4-methylpyridine gave the corresponding 1,2-dihydro-2-silanaphthalene derivatives (4) in 34-82% yields.

DABCO-promoted synthesis of pyrazoles from tosylhydrazones and nitroalkenes.

An efficient synthesis of pyrazoles from tosylhydrazones and nitroalkenes was developed. In comparison with the previously reported 1,3-dipolar cycloaddition reaction of diazo compounds with electron-deficient alkenes or alkynes, this methodology proceeded with a sequential Baylis-Hillman/intramolecular cyclization mechanism and a variety of reversed regioselectivity products were prepared in g...

Synthesis and structures of gold and copper carbene intermediates in catalytic amination of alkynes

Metal carbenes are often proposed as reactive intermediates in the late transition metal-catalysed transformations of alkynes. Owing to their high reactivity, however, isolation and structural characterization of metal carbene intermediates in these transformations has remained unknown. Herein, we report the isolation of two acyclic gold and copper carbene intermediates in either Au(I)- or Cu(I...

Cascades to substituted indoles.

This paper describes the synthesis of dithioindoles from the free-radical cyclizations of arylisonitriles having pendant alkynes. Also described is the synthesis of substituted indoles and spiro-fused indoles from the coupling of dithioindoles with active hydrogen-containing compounds.

Oxidative Dehydrogenative Couplings of Pyrazol-5-amines Selectively Forming Azopyrroles

New oxidative dehydrogenative couplings of pyrazol-5-amines for the selective synthesis of azopyrrole derivatives have been described. The former reaction simultaneously installs C-I and N-N bonds through iodination and oxidation, whereas the latter involved a copper-catalyzed oxidative coupling process. The resulting iodo-substituted azopyrroles were employed by treatment with various terminal...

Gold(I)-catalyzed 5-endo-dig carbocyclization of acetylenic dicarbonyl compounds.

The importance of cyclopentanoid natural products continues to inspire the development of methods for the synthesis of 5-membered rings. For example, the Conia–ene reaction provides an atomeconomical synthesis of methylenecyclopentanes by the thermal cyclization of e-acetylenic carbonyl compounds. While the classic thermal reaction is limited to the exocyclic cyclization mode, group 6 metal com...
