highly diverse derivatives of β‐fluoro(phenylsulfonyl)ethylamine has been developed (see scheme) by use of a Mannich‐type reaction from their molecular subunits, α‐fluoro‐α‐nitro(phenylsulfonyl)methane (1 a) or α‐fluorobis(phenylsulfonyl)methane (1 b), formalin, and various primary and secondary amines. The products are obtained in high yields and selectivity even, in many cases, without the use of
没有亚胺!利用分子亚基α-氟-α-硝基(苯磺酰基)甲烷的曼尼希型反应,开发了一种直接多组分协议,用于合成高度多样化的β-氟(苯磺酰基)乙胺衍生物(参见方案)。 (1 a)或α-氟双(苯磺酰基)甲烷(1 b),福尔马林以及各种伯胺和仲胺。即使在许多情况下,无需使用碱也能以高收率和高选择性获得产物。
