β-Amino acids are useful tools in the design of peptidomimetics, and the development of new methods for their syntheses, particularly the synthesis of β2-amino acids, remains an important challenge. Here we report a new scalable route based on the aminomethylation of silyl ketene N,O-acetals by Mannich-type iminium electrophiles. (© Wiley-VCH Verlag GmbH & Co.
