precursors with 2,3-butadienyl(trimethyl)silane and related allenes in the presence of BF(3).OEt(2) provides good yields of N-protected 2-(aminomethyl)-substituted 1,3-dienes, which prove to be useful substrates for subsequent Diels-Alder and alkene metathesis reactions. [reaction: see text]
在BF(3).OEt(2)存在下,用2,3-丁二烯基(三甲基)硅烷和相关的烯基化合物处理各种N-酰基亚胺离子前体可提供良好收率的N-保护的2-(氨基甲基)-取代的1,3-二烯,被证明是用于随后的狄尔斯-阿尔德和烯烃复分解反应的有用底物。[反应:看文字]
