Dehydrooligopeptides. XVI. Convenient syntheses of two kinds of antrimycins Av and Dv containing dehydrovaline residues

Eight kinds of peptide antibiotics, antrimycins (1), consist of four sorts of unusual α-amino acids, that is, hydroxymethylserine, (2S,3S)-2,3-diaminobutanoic acid, (S)-2,3,4,5-tetrahydro-3-pyridazinecarboxylic acid, and dehydrovaline (ΔVal) or (E)-dehydr
