A newsyntheticapproach to protulactone A and several of its structural analogues, starting from d-galactose, has been developed. In a preliminary bioassay, all the compounds showed potent cytotoxicities. A structure–activity relationship analysis identified structural segments that are important for antiproliferative activity.
protulactone A 及其几种结构类似物的新合成方法,从d-半乳糖,已经开发出来。在初步生物测定中,所有化合物都显示出强大的细胞毒性。结构-活性关系分析确定了对抗增殖活性重要的结构片段。

Total Synthesis, Configuration Assignment, and Cytotoxic Activity Evaluation of Protulactone A
The first totalsynthesis and absolute configuration assignment of protulactone A (1) has been achieved. Four stereoisomers, 1a, ent-1a, 1b, and ent-1b, of this natural polyketide were prepared by chiral pool synthesis starting from l- and d-arabinose, respectively. The absolute and relative configurations of all isomers were assigned by single-crystal X-ray analysis. Target compounds were screened
