Fluoroacetone imines of cyclohexylamine, valinol O-methyl ether, and phenylalaninol O-methyl ether and 2-fluorocyclohexanone imines of cyclohexylamine and phenylalaninol O-methyl ether were prepared.The temperature-dependent, regioselective deprotonation of these imines was employed in highly regioselective alkylation reactions.The deprotonation of fluoroacetone cyclohexylimine on the carbon bearing fluorine yielded only a single stereoisomer as determined by low temperature 19F NMR.In contrast, deprotonation of fluoroacetone O-benzyloximes was not regiospecific under any of the conditions examined.
