The fluorination of amino-alcohols giving tertiary β-fluoroamines was studied synthetically and stereochemically. Configuration of initial and final products were assigned using 1H and 19F NMR. The fluorination of amino-alcohols with FAR is a stereospecific reaction with retention of configuration. Isomerically or optically pure compounds can be obtained. The fluorination with HF - pyridine mixture
合成和立体化学研究了氨基醇的氟化,生成叔β-氟胺。初始和最终产物的构型使用1 H和19 F NMR进行分配。氨基醇与FAR的氟化反应是立体定向反应,保留了构型。可以得到异构或光学纯的化合物。用HF-吡啶混合物氟化可优先得到苏式氟胺。
