  The natural polypropionate-derived esters of the mollusk Onchidium sp

  摘要：

  Eight new polypropionate-derived esters (5-8 and 10-13) have been isolated from pulmonate molluscs of the genus Onchidium collected in the South Pacific. The structures of these compounds were determined spectroscopically in particular by one- and two-dimensional NMR and low and high EIMS. The absolute of the seven asymmetric centers was determined by using the Trost-Mosher methodology. Saponification afforded two triols named onchitriol I and II (4 and 9, respectively). Compounds 4-13 displayed in vitro antitumor activity against several cell lines. Onchitriol I and II had antiviral activity also.

  The first total synthesis of onchitriol II, a cytotoxic metabolite of mollusc Onchidium sp., is described. It employs mild cyclization method [DMSO - (COCl)2 or Ph3P - CCl4] of triketides bearing optically active functional groups to the corresponding γ-pyrones as a key step. Additional synthesis of some diastereoisomers provided a possibility to revise the structure of closely related onchitriol I.

  描述了甲壳三醇II（一种软体动物Onchidium sp。的细胞毒性代谢产物）的第一个全合成。它采用温和的环化方法[DMSO-（COCl）2或Ph 3 P-CCl 4 ]，将带有光学活性官能团的三酮化合物与相应的γ-吡喃酮类化合物结合在一起，作为关键步骤。一些非对映异构体的额外合成提供了修改紧密相关的甲壳三酚I结构的可能性。
