3-Aryl-1-thioacylindoles were prepared by treating α-aryl-2-isothiocyanato-β-methoxystyrenes with organolithiums or Grignard reagents, followed by hydriodic acid catalyzed cyclization of the resulting adducts. A one-pot synthesis of 1-thiocarbamoylindoles was achieved by hydriodic acid mediated cyclization of the corresponding thiourea intermediates, prepared from α-substituted 2-isothiocyanato-β-methoxystyrenes
通过用有机锂或格氏试剂处理α-芳基-2-异硫氰酸根合-β-甲氧基苯乙烯,然后用氢碘酸催化所得加合物的环化反应来制备3-芳基-1-硫代酰基吲哚。1-硫代氨基甲酰基吲哚的一锅合成是通过氢碘酸介导的相应硫脲中间体的环化而完成的,该中间体是由α-取代的2-异硫氰酸根合-β-甲氧基苯乙烯和仲胺制备的。 杂环-吲哚-环化-异硫氰酸酯-有机金属试剂
