The ring-opening of cyclic sulfamidates and sulfates with α-fluorocarbanion generated from fluorobis(phenylsulfonyl)methane (FBSM) and subsequent reductive desulfonylation have been developed. This fluoromethylation approach allows access to γ- and δ-fluoroamines as well as γ- and δ-fluoroalcohols in high yields. The monofluoromethylation of cyclic sulfamidates with α-fluorocarbanion of ethyl 2-fluoroacetoacetate
已经开发出环状磺酰胺酯和硫酸酯与由氟代双(苯磺酰基)甲烷(FBSM)产生的α-氟碳负离子进行开环以及随后的还原脱磺酰化。这种氟甲基化方法可以高产率地获得 γ- 和 δ- 氟胺以及 γ- 和 δ- 氟醇。还描述了环状磺酰胺与 2-氟乙酰乙酸乙酯的 α-氟碳负离子的单氟甲基化。
