Syntheses of novel sugar amino acid derivatives with the 2-amino-D-arabino-hex-2- ulopyranosonic acid skeleton are described, with the anomeric centre being the α-C-atom of the amino acid unit. The starting material for the syntheses reported is 2-oxo-D-gluconic acid which has been obtained by fermentation of D-glucose. Starting from this source differently protected pyranoid α-sugar amino acids as well as derivatives like dipeptides could be synthesized.
Keywords: 2-oxo-D-gluconic acid, 2-oxo-D-gluconate, sugar amino acids, 2-amino-D-arabino-hex-2-ulopyranosonic acid
