SYNTHESES OF CYCLOTETRAPEPTIDES, AM-TOXIN ANALOGS, CONTAINING α-HYDROXYALANINE

Condensation of amide with α-keto acid to yield a α-hydroxyalanine (α-Hyala) or dehydroalanine residue was applied to syntheses of analogs of AM-toxins, cyclotetradepsipeptides.Cyclo(α-Hyala-L-Ala-L-Val-L-Phe-), cyclo(-α-Hyala-L-Ala-L-Hmb-L-Phe-) and cycl
