Phenolic esters are efficiently converted to 2-substituted benzothiazoles in a one-pot reaction by treatment with 2-aminothiophenol in the presence of a catalytic amount of K2CO3 in N-methyl-2-pyrrolidone (NMP) at 100 °C.
在 100 °C 的 N-甲基-
2-吡咯烷酮(
NMP)中,在一定量的 K2CO3 催化下,通过与 2-
氨基
苯硫酚的一锅反应,
酚酯可高效地转化为 2-取代的
苯并噻唑。
