Short-chain 3-fluoro-(dihydro)ceramide analogues are synthesized from L-serine using diethylaminosulfur trifluoride (DAST) as fluorinating agent. The apoptogenic activity of these compounds was measured in three different cell lines and compared with their hydroxylated counterparts.

Based on a literature precedent, preparation of methyl 4-azido-3,4,6-trideoxy-3-fluoro-alpha-D-mannopyranoside (18) was attempted via fluorination of methyl 4-azido-2-O-benzyl-4,6-dideoxy-alpha-D-altropyranoside with diethylaminosulfur trifluoride (DAST). Contrary to expectations, the reaction took place with retention of configuration at the site of the fluorination yielding methyl
