費里爾重排反應

費里爾重排反應（Ferrier rearrangement），由糖化學家羅伯特·費里爾（Robert J. Ferrier）首先報道。^[1]

反應機理

首先在路易斯酸（如氯化銦或三氟化硼）作用下，乙酸根離子離去，產生離域的氧雜烯丙基碳正離子(2)。接下來(2)原位與醇作用，生成2-糖苷的α-(3)和β-(4)異頭物，同時雙鍵遷移至3,4-位。^[2]

例子

路易斯酸	醇	條件	結果
InCl₃	甲醇	二氯甲烷溶劑	α:β = 7:1^[3]
二噁烷	水	加熱	75%產率^[4]
SnCl₄	甲醇	二氯甲烷溶劑，–78℃，10分鐘	83%產率，α:β = 86:14^[5]
BF₃·O(C₂H₅)₂	異丙醇	二氯甲烷溶劑，室溫，24小時	95%產率^[6]^[7]
ZnCl₂	乙醇	甲苯溶劑，室溫，30－60分鐘	65–95%產率，α:β = 89:11^[8]^[9]
BF₃·O(C₂H₅)₂	苄醇	二氯甲烷溶劑，–20℃至室溫，1小時	98%產率^[10]

改進法

生成C-糖苷

用矽烷替代醇，可得C-糖苷。如果矽烷為三乙基矽烷（R'=H），則反應後得到3,4-不飽和去氧糖。^[2]

含氮底物

1984年，Kozikowski 等報道了氮雜的費里爾重排，用於抗生素 streptazolin 的合成。^[11]
