The practical syntheses of a few oxazole α-dehydroamino acids and their dehydrodi- and tripeptides, which are important moieties and segments of berninamycin A, macrocyclic peptide antibiotic, were first accomplished.
首次完成了几种噁唑α-脱氢氨基酸及其脱氢二肽和三肽的实际合成,它们是大环肽抗生素贝宁霉素 A 的重要分子和片段。
Dehydrooligopeptides. XIV. Syntheses of 2-[(<i>Z</i>)-1-Amino-1-alken-1-yl]oxazole-4-carboxylic Acid and the Main Common Skeleton of Thiostrepton Peptide Antibiotics, A10255G and J
constructed from a novel 2-[(Z)-1-amino-1-propen-1-yl]oxazole-4-carboxylic acid, 2-(1-aminomethyl)- and 2-[(S)-1-aminoethyl]thiazole-4-carboxylic acid residues, besides L-threonine and dehydroalanine residues at the N- and C-termini, respectively. First, the general syntheses of various 2-[(Z)-1-amino-1-alken-1-yl]oxazole-4-carboxylic acid derivatives (11) and preparation of N-terminal dehydrodipeptides
