Treatment of the γ-N-hydroxylamino-α,β-acetylenic esters, obtained by the reaction of nitrones with alkyl 3-lithiopropiolates, with H2 over Raney nickel, followed by in situ protection of the formed amines, gives N-Boc-γ-amino esters. This method has been applied to a synthesis of (S) and (R)-Vigabatrin®.
在雷尼镍上用 H2 处理通过硝基烷基 3-硫代丙酸酯与δ-N-羟基氨基-δ,δ-乙炔酯反应得到的δ-N-羟基氨基-δ,δ-乙炔酯,然后对形成的胺进行原位保护,得到 N-叔丁氧羰基-δ-氨基酯。这种方法已用于合成 (S) 和 (R)-Vigabatrin® 。
