Abstract
A facile synthetic route for the preparation of N-protected γ-amino β-keto esters from amino aldehydes and ethyl diazoacetate is described. The two component coupling is facilitated by tin(II) chloride followed by semipinacol rearrangement leading to the product in quantitative yield. The reaction...
