The synthesis of polyhydroxylated 1,1-difluoro-5-methylenecyclopentanes is described. The sequence involves an addition of PhSeCF2TMS to a tartrate-derived aldehyde or its corresponding tert-butanesulfinylimines followed by a radical cyclization. The use of a benzyl protected substrate led to an unproductive 1,5-hydrogen transfer after cyclization but the desired compound was eventually obtained from the unprotected substrate. A hydroboration/oxidation sequence was investigated on these 1,1-difluoro-5- methylenecyclopentanes as it would provide fluorinated carbasugars, a new and promising class of glycomimetics. Unfortunately, this reaction was poorly efficient and its regioselectivity not the expected one.
