  Oxidative rearrangement of sulfur-containing tertiary allylic alcohols: synthesis of 2-cycloalkenones bearing 3-[(phenylthio)methyl] and 3-[2-alkyl-1,3-dithian-2-yl] substituents

  摘要：

  Substrate 1-[(phenylthio)methyl]-2-cycloalkenols 3a-d and 1-[2-alkyl-1,3-dithian-2-yl]cyclohexenols 1a-d were prepared by adding [(phenylthio)methyl]lithium and 2-lithio-2-alkyl-1,3-dithianes, respectively, in the 1,2-mode to various 2-cycloalkenones. The ranges of yields for the additions were 86-95% in the (phenylthio)methyl series and 69-88% in the dithiane series. A representative compound from each range of substrate tertiary allylic alcohols was then treated with a series of oxochromium(VI)-amine reagents such as pyridinium chlorochromate (PCC), pyridinium dichromate (PDC), the Collins reagent (CrO3.Pyr2), and 2,2'-bipyridinium chlorochromate (BPCC). The oxochromium(VI)-amine reagents effected conversions of the representative substrates to the corresponding 3-[(phenylthio)methyl]- and 3-[2-alkyl-1,3-dithian-2-yl]-2-cycloalkenones 4a-d and 2a-d which were measured by gas chromatographic-mass spectral analysis. When comparing the efficiency of the range of oxochromium(VI)-amine reagents, PCC was found to give the best conversions to the corresponding transposed alpha,beta-unsaturated carbonyl compounds in both series of substrates while the Jones reagent gave only decomposed material and no recovery of substrate. Distinct improvements on the initial PCC protocol using silica gel as an in situ adsorbent and promotion by ultrasound were then established with a range of substrate tertiary allylic alcohols while comparing sonicated versus nonsonicated experiments. The isolated yields of transposed products were found to be increased as much as 60 % in the dithiane series and 9 % in the (phenylthio)methyl series with the application of high-intensity ultrasound. Prolonged exposure of the substrate (3a) in the (phenylthio)methyl series to the PCC/silica reagent system resulted in the recovery of the corresponding sulfone (5), the identity of which was confirmed by selective oxidation of the transposed enone (4a) with m-chloroperbenzoic acid.

• Generation of<i>α</i>-Alkylthio Radicals by Photoinduced One-Electron Oxidation of<i>α</i>-Stannyl Sulfides and Their Use for Carbon-Carbon Bond Formation

  日期：1997.2

  Cation radicals, generated from α-stannyl sulfides by the photoinduced single electron transfer, cleave into α-alkylthio radical intermediates with the elimination of the stannyl group. The α-alkylthio radicals thus formed are utilized for carbon-carbon bond forming reactions.

  通过光诱导的单电子转移，从α-锡基硫化物生成的阳离子自由基会裂解成α-烷硫基自由基中间体，同时消除锡基团。形成的α-烷硫基自由基可用于碳-碳键形成反应。
