The total synthesis of destruxin E (1) has been achieved for the first time, and the stereochemistry of its chiral center at the epoxide has been determined to be (S). The cyclization precursor 3a was synthesized by solid-phase peptide synthesis. Macrolactonization of 3a utilizing MNBA-DMAPO, followed by formation of the epoxide, then furnished destruxin E. Its diastereomer, epi-destruxin E (2), was
首次获得了destruxin E(1)的全合成,并且其手性中心在环氧化物上的立体化学被确定为(S)。通过固相肽合成来合成环化前体3a。利用MNBA- DMAPO对3a进行大分子内酯化,然后形成环氧化物,然后得到destruxinE 。其非对映异构体Epi- destruxin E(2)也以相同的方式合成。此外,生物学评估表明,destruxin E的V-ATPase抑制活性比Epi- destruxin E的高10倍。
