标题 :Electrochemical activation of organic disulfides for electrophilic substitution
发明人：GLASS RICHARD S; JOUIKOV VIATCHESLAV V; BOJKOVA NINA V
权利人:UNIV ARIZONA
摘要:Electrochemical oxidation of organic disulfides is conducted in an electrolytic solution containing an arene (e.g., anthracene, acenaphthylene, phenanthrene), and depending on the arene used and/or the product desired, an organic base (e.g., pyridine) to effect the synthesis of organothiated products in good yields.

标 题 :Electrochemically generated organothiating reagents and their use
发明人：GLASS RICHARD S; JOUIKOV VIATCHESLAV V
权利人:UNIV ARIZONA
摘要:Electrolysis of organic disulfides in liquid sulfur dioxide is used to obtain organothiating agents, which can then be reacted with appropriate substrates to effect the synthesis of organothioaromatic compounds efficiently and in high yields. With appropriate phenolic compounds, regioselective substitution occurs in which para substitution greatly exceeds ortho substitution.

摘要:A method is provided for synthesizing diaryl-substituted heterocyclic compounds, particularly 2,5-diaryl-substituted tetrahydrofurans and tetrahydrothiophenes. Methods for synthesizing starting materials and intermediates are provided as well. An important application of the invention is in the synthesis of CMI-392, (±)trans-2-[5-N'-methyl-N'-hydroxyureidyl-methyl)3-methoxy-4-p-chlorophenylthioethoxyphenyl]-5-(3,4,5-trimethoxyphenyl)-tetrahydrofuran, a highly effective agent in treating inflammatory and immune disorders. The invention also encompasses novel compounds useful as starting materials and intermediates in the synthetic processes disclosed.
