facile and practical method for the preparation of (E)-β-arylenamides [(E)-N-(1-arylprop-1-en-2-yl]acetamides] has been developed by reductive acetylation of the corresponding oximes with iron(II) acetate as the reducing reagent. Employment of hexamethylphosphoramide as the solvent was found to be critical for the high E/Z selectivity. The methodology has been applied in efficient syntheses of a key
摘要 通过用铁还原相应的肟,开发了一种简便实用的制备(E)-β-芳基酰胺[(E)-N-(1-芳基丙-1-烯-2-基]乙酰胺]的方法(II)乙酸盐作为还原剂发现使用六甲基磷酰胺作为溶剂对高E / Z选择性至关重要,该方法已用于通过不对称氢化有效合成坦索罗辛的关键手性中间体。 通过用铁还原相应的肟,开发了一种简便实用的制备(E)-β-芳基酰胺[(E)-N-(1-芳基丙-1-烯-2-基]乙酰胺]的方法(II)乙酸盐作为还原剂发现使用六甲基磷酰胺作为溶剂对高E / Z选择性至关重要,该方法已用于通过不对称氢化有效合成坦索罗辛的关键手性中间体。
