Abstract
| - Cyclodepsipeptides incorporating a sugar amino acid (alcohol) have been synthesized. A three-component reaction ofa sugar amino acid (SAA) derivative, an aldehyde, and adipeptide isonitrile in refluxing methanol afforded thecorresponding 5-aminooxazole which, after saponification,underwent a trifluoroacetic acid promoted macrocyclizationto furnish the cyclic sugar amino acids.
