A convenient, metal-free intramolecular aminofluorination of alkenes has been developed. Employing readily available PhI(OPiv)2 and hydrogen fluorideâpyridine in the presence of BF3·OEt2, tosyl-protected pent-4-en-1-amines were converted to 3-F-piperidines in one step in good yields as well as high stereoselectivity.
一种便利的无金属分子内氨基氟化反应已被开发用于烯烃。在BF3·OEt2的存在下,利用容易获得的PhI(OPiv)2和氟化氢-吡啶,将保护基为磺酰基的五碳-4-烯-1-胺在一步反应中转化为3-F-哌啶,产率良好且立体选择性高。
