【摘要】 采用山苍子油提取得到的柠檬醛和丙酮等为主要原料合成鸢尾酮。合成分三步完成。先用柠檬醛与丙酮在碱的催化下生成假紫罗兰酮,收率为93．2%。假紫罗兰酮甲基化生成假鸢尾酮,收率为52．3%。假鸢尾酮环化得到鸢尾酮,收率为98．3%。合成的总收率较高达到47．9%。并对合成的鸢尾酮进行了理化性质、光谱、色-质和调香评香等的确证。更多还原

【Abstract】 Irone was obtained through three steps reactions with citral and acetone.Citral reacted with acetone in the base catalyst to give pseudoionone.The yield was 93.2% .After methylating,pseudoirone was prepared.The yield was 52.3%.Pseudoirone cyclized with mixing acid as cyclizing agent to give irone.The yield was 98.3%.The total yield was higher to give 47.9% and the reaction was easy to control.The product was detemined by spectro- scope,Ms-Gc,blend and so on.更多还原
