Trimethylsilyl g-silylated crotonates 1 smoothly react with NsONHCO2Et under basic conditions to give vinylglycine derivatives 2 in fairly good yields (65%). The reaction may proceed through addition of carbethoxynitrene to the double bond of the crotonate with subsequent elimination of the silyl group.

Keywords: Nitrene; Trimethylsilyl crotonate; Vinylglycine.
