A new and environmentally friendly Fmoc protection of a variety of aliphatic and aromatic amines, amino acids, amino alcohols and amino phenols is reported in aqueous media under mild and catalyst-free conditions. The reaction proved to be chemoselective in presence of ambident nucleophiles.
A simple, eco-sustainable method for the N-(9-fluorenylmethoxycarbonyl) (N-Fmoc) protection of various structurally amines under ultrasonic irradiation is reported. The corresponding N- Fmoc derivatives were obtained in good to excellent yields within short reaction time. The reaction proceeds without the formation of any side product. Mildness, efficiency and easier work are the main advantages of this new protocol.
