  Solvent-Free Conversion of Thioamides to Thioesters

  摘要：

  [image omitted] Diverse thioesters were efficiently prepared via the solvent-free reaction of thioamide derivatives with alkyl halides in the presence of catalytic amounts of 1,4-diazabicyclo[2.2.2]octane (DABCO) in small quantities of water and in good to excellent yields.

  N′-diphenylthiourea, triethylamine, and primary alkyl halides is described. Microwave-assisted heating and a catalytic amount of 4-(dimethylamino)pyridine (DMAP) further improved the yields. Both aromatic and aliphatic carboxylic acids were converted to the corresponding thioesters, and many functional groups were compatible with this reaction. Several possible reaction intermediates were investigated, and the

  Thioesters were efficiently prepared via the direct reaction of tertiary thioamides and alkyl halides in water, and in the presence of catalytic amounts of NaI, hexadecyltrimethylammonium bromide (HTAB), and 1,4-diazabicyclo[2.2.2]octane (DABCO). Hence, thioamides smoothly undergo an S-alkylation with alkyl halides in aqueous media following by hydrolysis to afford the corresponding thioesters in very good to excellent yields.

  在 NaI、十六烷基三甲基溴化铵（HTAB）和 1,4-二氮杂双环[2.2.2]辛烷（DABCO）的催化下，通过叔硫酰胺和烷基卤化物在水中的直接反应，可以高效地制备硫代酯。因此，硫代酰胺在水介质中可以顺利地与烷基卤化物发生 S-烷基化反应，然后通过水解得到相应的硫代酯，收率非常好甚至非常高。
