An efficient synthesis of 3-vinylpyrroles by Stille coupling reaction of 3-iodopyrroles with vinyltributyltin
摘要:
Several 3-vinylpyrrolic compounds with different functional groups have been synthesized by Stille coupling reaction of S-iodopyrroles with vinyltributyltin in 80-92% yields. Under the same reaction conditions it was found that 3-bromopyrroles gave the corresponding product in very poor yield, while 3-chloropyrroles were unreactive.
