4-甲磺酰基苯甲酸甲酯的应用与制备

4-甲磺酰基苯甲酸甲酯是一种芳基砜类化合物，可用作医药合成中间体和有机合成中间体，主要用于实验室研发过程和化工医药合成过程中。

制备方法

在反应管中加入262 mg对碘苯甲酸乙酯（分子量＝262.04，1.0 mmol），然后依次加入153 mg甲基亚硫酸钠盐（分子量＝102.09，1.2 mmol，含量80%）、28 mg L-脯氨酸钠盐（分子量＝137.05，0.2 mmol）和19 mg CuI（分子量＝190.45，0.1 mmol），并使用2 ml DMSO作为溶剂。在氮气保护下，将混合物置于80℃油浴中反应36小时后冷却，加入4毫升水，用10毫升乙酸乙酯萃取三次。萃取液经饱和食盐水洗涤、无水硫酸钠干燥后过滤，滤液通过减压蒸馏，并使用硅胶柱分离（淋洗液为石油醚∶乙酸乙酯＝3∶1），最终得到158 mg产物4-甲磺酰基苯甲酸甲酯，产率为77%。

• Correlation of carbon-13 substituent-induced chemical shifts:Meta- andpara-substituted methyl benzoates
  作者：Miloš Buděšńský、Otto Exner

  DOI：10.1002/mrc.1260270612

  日期：1989.6

  Carbon‐13 NMR spectra are reported for 69 substituted methyl benzoates in deuteriochloroform or in its mixture with dimethyl sulphoxide‐d6. The substituent‐induced chemical shifts (SCS) of the CO carbon correlate poorly with dual substituent parameters (DSP) in all possible modifications, and for meta derivatives in particular this correlation is both overpara meterized and imprecise. A much better

We have now achieved a cross-coupling approach to this transformation using nickel, a bulky N-heterocyclic carbene ligand, and alkyl organoboron coupling partners. 65 alkyl ketones bearing diverse functional groups

  We have developed an eco-friendly and chemo-selective photocatalytic synthesis of sulfoxides or sulfones via oxidation of sulfides (thioethers) at ambient temperature using air or O2 as the oxidant. An inexpensive thioxanthone was used as the photocatalyst. Our method offers excellent chemical yields and good functional group tolerance.

  The amide derived from 4-hydroxy-l-proline and 2,6-dimethylaniline is a powerful ligand for Cu-catalyzed coupling of (hetero)aryl halides with sulfinic acid salts, allowing the formation of a wide range of (hetero)aryl sulfones from the corresponding (hetero)aryl halides at considerably low catalytic loadings. The coupling of (hetero)aryl iodides and sodium methanesulfinate proceeds at room temperature
