仙客来醛(英語:Cyclamen aldehyde)是一种有机化合物,化学式为C13H18O。仙客来醛具有山谷百合味香气,其气味及强度与间位异丙基的异构体相似[3],可用于香水制造[4]

合成

[编辑]

仙客来醛可由对异丙基-α-甲基肉桂醛在负载氧化铝(或负载二氧化硅)的催化氢化得到。[5]β-甲基-4-异丙基苯丙醇被马丁试剂氧化,也能制得仙客来醛。[6]

反应

[编辑]

仙客来醛和盐酸羟胺四氯化钛-吡啶体系中反应,可以得到α-甲基-4-异丙基苯丙腈,[7]羟胺-O-磺酸乙酸水溶液中也能完成这一转化。[8]

它和4-硝基苯甲醛吡咯烷-乙酸催化下于二甲基亚砜中反应,经烯胺中间体,可以得到β-羟基-α-甲基-α-(4-异丙基苄基)-4-硝基苯丙醛。[9]

在催化下,它可以和乙二醇形成缩醛[10]

它和氟试剂乙酰丙酮亚铁催化下于乙腈中反应,得到β-氟-α-甲基-4-异丙基苯丙醛(syn:anti=2:1)。[11]
