Application

4-Nitrophenyl 2-(trimethylsilyl)ethyl carbonate can be used as:
  • A protecting group for an amine in one of the key synthetic steps of kottamide E total synthesis.
  • A starting material to prepare a cis-butene derivative, which is used as a polymer terminating agent in the synthesis of monotelechelic glycopolymers.

2-(Trimethylsilyl)ethyl-4-nitrophenyl carbonate has been prepared as a new reagent for the introduction of the 2-(trimethylsilyl)ethyloxycarbonyl group into amino acids or amino acid derivatives. The resulting N alpha-protected amino acids were found to represent suitable intermediates for the synthesis of peptides.
