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。
