The one-pot synthesis of a new substituted 1,2,3,4-tetrahydrocarbazoles has been described via Petasis reactions. These tetrahydrocarbazoles exhibits various medicinal importance and might be suitable for elaboration into larger peptides at carboxy termini. The scope and limitations of this method have been examined.

N-1-(Carbamate protected)-N-2-(alkyl or aryl substituted) hydrazines can serve as amine substrates for the Petasis boronic acid-Mannich reaction, providing a practical synthetic route for the preparation of alpha-hydrazinocarboxylic acids. The scope and limitations of this method have been examined. (C) 2002 Published by Elsevier Science Ltd.
