The reductive amination of an aminoacidderived glyoxal, with the free amino group of a protected aminoacid or oligopeptide fragment, has been developed as a simple and efficient method for the preparation of ketomethylene amino pseudo-oligopeptide isosteres Aa psi(COCH2NH)Aa. Trichlorosilane-DMF is the reagent of choice for the reduction.
Several novel thiazoles with side chains derived from natural amino acids and a dipeptide have been synthesised from N-protected alpha-amino glyoxals and cysteine. (C) 2000 Elsevier Science Ltd. All rights reserved.
