synthesized by a convergent approach. The asymmetric synthesis of β-hydroxy acid fragment was achieved by using chiral oxazaborolidinone mediated aldol reaction. The oxazole ring was constructed from N-acylthreonine via side-chain oxidation and cyclodehydration. The synthesis of the linear peptide was carried out in a stepwise manner from the cyclic hydroxamic acid fragment, and the final deprotection provided
通过收敛方法有效地合成了阿米他汀A,一种线性脂肽,是一种来自放线菌的人肿瘤细胞系的生长抑制剂。β-羟酸片段的不对称合成是通过手性草氮杂硼烷酮介导的羟醛反应实现的。由N-酰基苏氨酸经侧链氧化和环脱水作用构建恶唑环。线性肽的合成是从环状异羟肟酸片段逐步进行的,最终的脱保护作用提供了阿米他汀A。
