仙客來醛(英語:Cyclamen aldehyde)是一種有機化合物,化學式為C13H18O。仙客來醛具有山谷百合味香氣,其氣味及強度與間位異丙基的異構體相似[3],可用於香水製造[4]

合成

仙客來醛可由對異丙基-α-甲基肉桂醛在負載氧化鋁(或負載二氧化硅)的催化氫化得到。[5]β-甲基-4-異丙基苯丙醇被馬丁試劑氧化,也能製得仙客來醛。[6]

反應

仙客來醛和鹽酸羥胺四氯化鈦-吡啶體系中反應,可以得到α-甲基-4-異丙基苯丙腈,[7]羥胺-O-磺酸乙酸水溶液中也能完成這一轉化。[8]

它和4-硝基苯甲醛吡咯烷-乙酸催化下於二甲基亞碸中反應,經烯胺中間體,可以得到β-羥基-α-甲基-α-(4-異丙基苄基)-4-硝基苯丙醛。[9]

在催化下,它可以和乙二醇形成縮醛[10]

它和氟試劑乙酰丙酮亞鐵催化下於乙腈中反應,得到β-氟-α-甲基-4-異丙基苯丙醛(syn:anti=2:1)。[11]
