An efficient preparation of β-amino-2a,α-difluoroketones 4 was developed. Reactions of 1,1-difluorovinyl methyl esters 1 with N-acyliminium intermediates, generated by treating biscarbamates 2 with trifluoromethanesulfonic anhydride (Tf2O) in t

1,1-Dialkoxy-2-azapropenylium salts 1 were synthesized by alkylation at the oxygen atom of N-methylenecarbamates 4 with trialkyloxonium salts 5, in cases, where steric hindrance makes N-alkylation difficult (4a); otherwise the iminium salts 6 are formed p
