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
