A regioselective coupling of ethyl 2-(bromomethyl)-3-cyanoacrylate and primary amines is described to give ethyl 2-[(alkylamino)(cyano)methyl] acrylates in good yields. Whereas the conversion of allyl bromide in the presence of TEAF leads to the first synthesis of ethyl 3-cyano-2-(hydroxymethyl) acrylate.
描述了2-(溴甲基)-3-氰基丙烯酸乙酯和伯胺的区域选择性偶联,以良好的产率得到2-[((烷基氨基)(氰基)甲基]丙烯酸乙酯。而在TEAF存在下烯丙基溴的转化导致3-氰基-2-(羟甲基)丙烯酸乙酯的首次合成。
