  Synthesis of 2‘-Alkylspiro[2-X-cyclohexan-1,3‘-3‘H-indole] (X = H; X = CH₃) by an Unexpected Reaction between an Organomagnesium Halide and 2‘-Methylspiro[2-X-cyclohexan-1,3‘-3‘H-indole]. X-ray Structure of a Fluorescent Dimeric Compound

  摘要：

  The reaction of 2'-methylspiro[cyclohexan-1,3'-3'H-indole] (1a) with methylmagnesium iodide gives 2'-ethyl-, 2'-isopropyl-, and 2'-tert-butylspiro[cyclohexan-1,3'-3'H-indole] as the unexpected 2'-methyl insertion products; their presence and ratio are dependent upon the reaction conditions. Influence of a methyl substituent in 2'-methylspiro[2-methylcyclohexan-1,3'-3'H-indole] (1b) on the reaction with methylmagnesium iodide has been analyzed; the 2'-ethyl (2b) and 2'-isopropyl (3b) derivatives were obtained as the insertion products together with a luminescent compound that was identified by X-ray diffraction analysis as meso-(1R,2S),(1S,2R)-alpha,beta-di{(2'-(spiro[2 -methylcyclohexan-1,3'-3'H-indolyl]}ethene (10). The reaction of 1a or 1b with some active organomagnesium halides (allyl or benzyl) afforded the 2'-methyl-2'-alkyl-3'H-indole derivative (allyl, 5a or 5b; benzyl, 6a) as an apparent addition product. The reaction possibly occurs through a mechanism of radical intermediates.

  accessible chiral sulfinamide 2 has been developed as the first highly efficient and enantioselective organocatalyst relying solely on a chiral sulfur center for stereochemical induction. In the presence of 20 mol % of 2, a broad range of N-aryl ketimines 1 were reduced by trichlorosilane to produce amines 3 in high yield and enantioselectivity. [reaction: see text]

  The Zn-promoted direct reduction of various ketones, including alkyl aryl ketones, α- and β-keto esters, α- and β-keto amides, into the corresponding alcohols with polymethylhydrosiloxane (PMHS) in protic conditions is reported. The reaction proceeds chemoselectively under smooth conditions, with simple catalyst combinations based on a zinc precursor [ZnEt2, Zn(OMe)2, Zn(OH)2] and a 1,2-diamine ligand
