Novel racemic and enantiomerically enriched unsaturated tryprostatin B analogues were synthesised by an enaminone-based strategy. The synthesis also features a novel copper(I)-catalysed dipeptide formation. In addition, the enantiomeric purity of an enantiomerically enriched analogue was determined by 1H NMR spectroscopy by use of our own chiral solvating agent.
通过一种基于烯胺酮的策略合成了新型外消旋和对映体富集的不饱和胰岛素 B 类似物。该合成方法还采用了新颖的铜(I)催化二肽形成技术。此外,利用我们自己研制的手性溶解剂,通过 1H NMR 光谱测定了对映体富集的类似物的对映体纯度。
