Abstrtact A series of 2,2-difluoro-2-arylethylamines was synthesized as fluorinated analogs of octopamine and noradrenaline with the expectation of bioisosteric OH/F exchanges. The syntheses of these compounds were performed by a Suzuki–Miyaura cross-coupling reaction of 4-(bromodifluoroacetyl)morpholine with aryl boronic acids to produce the intermediate 2,2-difluoro-2-arylacetamides, followed by transformation of difluoroacetamide to difluoroethylamine.

作为章鱼胺和去甲肾上腺素的氟化类似物的 2,2-二氟-2-芳基乙胺的合成

摘要 一系列 2,2-二氟-2-芳基乙胺被合成为章鱼胺和去甲肾上腺素的氟化类似物，预期生物等排 OH/F 交换。这些化合物的合成通过 4-（溴二氟乙酰基）吗啉与芳基硼酸的 Suzuki-Miyaura 交叉偶联反应生成中间体 2,2-二氟-2-芳基乙酰胺，然后将二氟乙酰胺转化为二氟乙胺。
