| titleOfInvention | A kind of preparation method of 5-methyl-5-phenyl-4-arylsulfonyl-furan-2(5H)-one compound |
| abstract | The invention discloses a preparation method of a 5-methyl-5-phenyl-4-arylsulfonyl-furan-2(5H)-ketone compound. The compound has the structure shown in formula (I), and its The preparation method comprises: under the condition of inert gas in an organic solvent, heating a phenyl diazonium salt and a compound providing sulfur dioxide to generate a phenylsulfonyl radical, the phenylsulfonyl radical and 4-phenylpentane-2,3-di The alkenoic acid is reacted to cyclize, and a single electron transfer occurs with the catalyst Cu(OAc) 2 to obtain 5-methyl-5-phenyl-4-arylsulfonyl-furan- having the structure shown in formula (I). 2(5H)-ketone compound. The method of the invention can synthesize the sulfonyl-containing furan-2(5H)-one compound under very mild and simple conditions, can be used for large-scale industrial preparation, and has good application prospects in scientific research and industrial fields. |
