  Determination of the Relative and Absolute Stereochemistry of Fostriecin (CI-920)

  摘要：

  The absolute stereochemistry of fostriecin (1, CI-920), a potent antitumor antibiotic presently in Phase I clinical trials at NCI, was determined to be 5R,8R,9R,11R. 2D H-1-H-1 NMR. NOE experiments conducted on the cyclic phosphate derivative 2 and acetonide revealed a syn-diol stereochemical relationship between C8 and C9 and an anti-diol stereochemical relationship between C9 and C11, respectively. The 5R absolute configuration assignment was confirmed by synthesis of the degradation product 8 previously disclosed. Additional degradation studies of 1 to provide 7 and chiral-phase HPLC comparison with a sample of known chirality established the absolute stereochemistry of C11 to be R. This, along with the relative stereochemical assignments established the full set of absolute stereochemistry assignments for 1.

  trahydrofurans with TiCl4 results in cleavage of the heterocyclic ring with intervention by the appropriately situated ester group to form intermediates which, on work-up and hydrolysis, furnish 1,4-diols.

  用TiCl 4处理3-芳酰氧基-和2-（芳酰氧基甲基）四氢呋喃可导致杂环的裂解，同时通过适当定位的酯基的干预形成中间体，该中间体在后处理和水解时提供1,4-二醇。
