Difluoro(trimethylsilyl)acetamides 7 have been prepared from chlorodifluoroacetamides 5 by electrochemical silylation. When condensed with carbonyl compounds, they were shown to be precursors of 2,2-difluoro-3- hydroxyacetamides 8. N-(p-Methoxyphenyl)-2,2-difluoro-3-hydroxy-4- methylvaleramide (8a) has been converted into the correspending 3,3-difluoroazetidinone 9a. This new route to 3,3-difluoroazetidinones is shown to be an alternative to the one utilizing the condensation of ethyl difluoro(trimethylsilyl)acetate with imines. Wiley-VCH Verlag GmbH & Co.
