  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.
