A general methodology is described that allows the solid-phase synthesis of depsides and depsipeptides from chiral alpha-hydroxy- and alpha-amino acids. The results of studies with different protecting groups for the alpha-hydroxy acids and coupling systems for depside bond formation are presented. The oligomers were prepared using a Wang-type linker with final TFA/CH(2)Cl(2) cleavage. Depside linkage

general solid phase methodology for the synthesis of depside and depsipeptide chains from optically active α-hydroxy acids and α-amino acids is reported. The automated preparation of depsides (97% yield per cycle) made up from the same enantiomer [i.e. H-[(S)-Man]8-OH, 1] † by both enantiomers [i.e. H-[(R)-Man-(S)-Man]4-OH, 2], or by different hydroxy acids in the same chain [i.e. H-[(S)-Lac-(S)-Hiv]3-OH
N-Aminodipeptide derivatives can be easily prepared with highopticalpurity on solid phase via a Mitsunobu protocol between a solid supported α-hydroxyacid and a free phthaloylated α-Z-N-aminohydrazide.
通过固载的α-羟基酸和游离的邻苯二甲酰化的α- Z - N-氨基酰肼之间的Mitsunobu方案,可以容易地在固相上以高光学纯度制备N-氨基二肽衍生物。

corresponding carboxylic acids (acetic acid, formic acid, lactic acid and glyceric acid) accumulated over time. Both Nε-lysine amides and carboxylic acids were thus determined as stable Maillard end products. Results of model incubations suggested the synthesis of amides to be mechanistically closely related to the formation of their corresponding carboxylic acids by β-dicarbonyl cleavage. Due to the
