This paper describes the solvent-assisted addition of trimethylsilyl cyanide (TMSCN) to cyclic α-fluorinated ketones. In DMF, this method gives TMS-protected cyanohydrins in good yields (70–95 %) and with good selectivities (dr up to 22:1), and the products are readily reduced to the corresponding fluorinated 1,2-amino alcohols.
