This manuscript describes the electrochemical synthesis of 17 different glycosyl fluorides in 73-98% yields on up to a 5 g scale that relies on the use of SF6 as an inexpensive and safe fluorinating agent. Cyclic voltammetry and related mechanistic studies carried out subsequently suggest that the active fluorinating species generated through the cathodic reduction of SF6 are transient under these reductive conditions and that the sulfur and fluoride byproducts are effectively scavenged by Zn(II) to generate benign salts.

This study describes a new convenient method for the photocatalytic generation of glycosyl fluorides using sulfur(VI) hexafluoride as an inexpensive and safe fluorinating agent and 4,4′-dimethoxybenzophenone as a readily available organic photocatalyst. This mild method was employed to generate 16 different glycosyl fluorides, including the substrates with acid and base labile functionalities, in yields of 43%-97%, and it was applied in continuous flow to accomplish fluorination on an 7.7 g scale and 93% yield.

Total syntheses of BE-12406 A (3a) and its C(8)-vinyl analog (3c) are described. The key step is the selective O-glycosylation of naphthol (4)with L-rhamnopyranosyl fluoride (5) by employing Cp2HfCl2-AgClO4 in fluorobenzene at -20°C in the presence of a hindered base, 2,6-di-t-butyl-4-methylpyridine (12), affording O-glycoside (11) in good yield.
