1–2 equivalents of water can be performed efficiently by using RuH2(PPh3)4 catalyst to give the corresponding amides. Under the similar reaction conditions, δ-ketonitriles can be converted into the corresponding ene-lactams, which are versatile synthetic intermediates. The efficiency of the reaction is demonstrated by the short-step synthesis of (−)-pumiliotoxin C.
通过使用RuH 2(PPh 3)4催化剂生成相应的酰胺,可以有效地用1-2当量的水进行腈水合。在相似的反应条件下,δ-乙腈可以转化为相应的烯-内酰胺,它们是通用的合成中间体。通过(-)-pumiliotoxin C的短步合成证明了反应的效率。
