  Scalable Solution-Phase Synthesis of the Biologically Active Cyclodepsipeptide Destruxin E, a Potent Negative Regulator of Osteoclast Morphology

  摘要：

  The scalable solution-phase synthesis of the cyclodepsipeptide destruxin E (1) has been achieved. Diastereoselective dihydroxylation of the terminal alkene in a 2-alkoxy-4-pentenoic amide, 7, was successfully accomplished utilizing (DHQD)(2)PHAL as the chiral ligand, and it was found that the use of the L-proline moiety in the substrate as a chiral auxiliary was essential for the induction of high diastereoselectivity to afford the key compound 4 on a gram scale. MNBA-mediated macrolactonization of 3 was also performed without formation of the dimerized product even under higher-dilution conditions, and it is noteworthy that the internal hydrogen bonds and s-cis configuration of the amide bond between N-methylalanine and N-methylvaline in the cyclization precursor 3 would assist in the macrolactonization to provide the macrolactone 2 without forming a dimerized product. Finally, epoxide formation in the side chain afforded destruxin E (1) on a gram scale in high purity (>98%).

  Destruxin E的合成，结构测定和生物学评估

  摘要：

  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。

  gave 18 member destruxin E analogues 6. Biological evaluation of analogues 6 indicated that the N‐MeAla residue was crucial to the induction of morphological changes in osteoclast‐like multinuclear cells (OCLs). Based on structure–activity relationships, azido‐containing analogues 15 were then designed for use as a molecular probe. The synthesis and biological evaluation of analogues 15 revealed that
