Dual C-13 and deuterium labeled perillic acid, [(1,1-dideuterio-1-13C-2-methyl)ethenyl]-1-cyclohexene-1-carboxylic acid (6) and deuterated perillyl alcohol, [(2,2-dideuterio-1-methyl)ethenyl]-1-deuteriohydroxymethyl-1-cyclo-hexene (9) were synthesized from commercially available (4S)-(-)-perillaldehyde (1). Compound 1 was first protected with ethylene glycol to yield the ethylene ketal followed by
双 C-13 和氘标记紫苏酸,[(1,1-dideuterio-1-13C-2-methyl)ethenyl]-1-环己烯-1-羧酸 (6) 和氘代紫苏醇,[(2,2 -双氘代-1-甲基)乙烯基]-1-氘代羟甲基-1-环己烯(9)由市售的(4S)-(-)-紫苏醛(1)合成。化合物 1 首先用乙二醇保护得到亚乙基缩酮,然后用 OsO4/NalO4 氧化以裂解末端双键,得到关键中间体酮,4-乙酰基-1-环己烯-1-甲醛缩酮 (3)。然后通过与制备的 Ph3P13CD3l 或 Ph3PCD3l 的 Wittig 反应将 3 转化为标记的紫苏醛,然后去保护得到标记的紫苏醛,[(2,2-dideuterio-2-13C-1-甲基) 乙烯基]-1-环己烯-1 - 甲醛 (5) 或 [(2, 2-dideuterio-1-methyl)ethenyl]-1-cyclohexene-1-carboxaldehyde
