Abstract

The anchoring of an α‐amino‐acid derivative by its amine function on to a solid support allows some chemical reactions starting from the carboxylic acid function. This paper describes the preparation of α‐amino aldehydes linked to the support by their amine function. This was performed by reduction with LiAlH~4~ of the corresponding Weinreb amide linked to the resin. The aldehydes obtained were then involved in Wittig or reductive amination reactions. In addition, the linked Weinreb amide was reacted with methylmagnesium bromide to yield the corresponding ketone. After cleavage from the support, the compounds were obtained in good to excellent yields and characterized. Copyright © 2004 European Peptide Society and John Wiley & Sons, Ltd.
