    • Methods for synthesizing deuterated vinylpyridine compounds of the Formula (1), wherein the method includes: (i) deuterating an acyl pyridine of the Formula (2) in the presence of a metal catalyst and D2O, wherein the metal catalyst is active for hydrogen exchange in water, to produce a deuterated acyl compound of Formula (3); (ii) reducing the compound of Formula (3) with a deuterated reducing agent to convert the acyl group to an alcohol group, and (iii) dehydrating the compound produced in step (ii) with a dehydrating agent to afford the vinylpyridine compound of Formula (1). The resulting deuterated vinylpyridine compounds are also described.
    • 用于合成式(1)的氘化乙烯基吡啶化合物的方法,其中所述方法包括:(i)在金属催化剂和D 2 O存在下使式(2)的酰基吡啶氘化,其中所述金属催化剂用于氢交换 在水中制备式(3)的氘代酰基化合物; (ii)用氘代还原剂还原式(3)的化合物以将酰基转化为醇基,和(ⅲ)用脱水剂将步骤(ⅱ)中生成的化合物脱水得到式(Ⅴ)的乙烯基吡啶化合物, (1)。 还描述了所得的氘代乙烯基吡啶化合物。
