Ring-opening fluorination reactions of epoxides using tetrabutylammonium bifluoride (TBABF)-KHF 2 , or Et 3 N-3HF under microwave irradiation were applied for the introduction of a fluorine atom into the carbohydrate molecules. When TBABF-KHF 2 was used as the fluorination reagent, a fluorine atom was introduced regioselectively and various functional groups can tolerate the...
Deoxyfluorination of alcohols was carried out using N,N-diethyl-α,α-difluoro-(m-methylbenzyl)amine (DFMBA). Primary alcohols were effectively converted to fluorides under microwave irradiation or conventional heating. Deoxyfluorination of an anomeric hydroxy group in sugars by DFMBA proceeded at below room temperature and glycosyl fluorides could be obtained in good yields. The deoxyfluorination reaction...
