The reaction of fluoroalkanesulfonyl azides with several silylketeneacetals has been investigated. 1-Ethoxyl-1-trimethylsilyloxy-ethylene reacted readily with azides to afford N-fluoroalkanesulfonyl substituted glycinates in good yields. However, reaction of mono- or dialkyl-substituted silylketeneacetals with azides gave rise to N-substituted α-aminoesters and substituted N-perfluoroalkanesulfonyl
