The stereoselective synthesis of an amino acid component called Fragment D, N,O-diprotected 2-[(1S,3S)-1-amino-3-carboxy-3-hydroxypropyl]thiazole-4-carboxylic acid of a macrobicyclic peptide antibiotic nosiheptide, was achieved by two routes. The dipeptide, Fragment B-C, 2-[(Z)-1-(N,O-isopropylidene-L-threonylamino)-1-propenyl]thiazole-4-carboxylic acid was also synthesized by the thiazole ring formation
一种氨基酸成分的立体选择性合成,称为片段 D,N,O-diprotected 2-[(1S,3S)-1-amino-3-carboxy-3-hydroxypropyl]thiazole-4-羧酸的大双环肽抗生素那西肽,是通过两条路线实现的。二肽,片段 BC,2-[(Z)-1-(N,O-isopropylidene-L-threonylamino)-1-propenyl]thiazole-4-羧酸也通过 (Z)-的噻唑环形成合成2-(N,O-双保护的 L-苏氨酰氨基)-2-丁烯硫酰胺与溴丙酮酸乙酯。通过使用缩合剂将两个组分偶联得到预期的三肽 2,它是那西肽的重要部分骨架。
