pure gamma-fluoroalkyl beta-amino sulfones are readily synthesized in three steps starting from fluorinated imidoyl chlorides and arylmethyl sulfones. A complementary two-step sequence starting from chiral fluorinated beta-amino sulfoxides has also been developed. To illustrate the application of this procedure, a new method for the synthesis of alpha-fluoroalkyl allylic amines in optically pure form involving
[反应:见正文]对映体纯的γ-氟烷基β-氨基砜很容易地从氟化亚氨基酰氯和芳基甲基砜开始,分三步合成。还开发了从手性氟化β-氨基亚砜开始的互补两步序列。为了说明该方法的应用,提出了一种新的合成光学纯形式的α-氟烷基烯丙基胺的方法,该方法涉及茱莉亚甲基化-脱磺酰基反应。
