Abstract
Treatment of disilyl ketene acetals with per(poly)fluoroalkanesulfonyl azides at 0 °C in acetonitrile afforded N-sulfonyl-protected α-amino acids in good yields. The method provided a novel and convenient access to N-sulfonyl-protected α-amino acids.
Key words
amino acids - amination - disilyl ketene acetals - fluoroalkanesulfonyl azides - sulfonyl-protected
