Triscutin molecular formula

Compound (98) showed a molecular formula of C90H122O12, according with its FAB-MS and 13C-NMR spectra. Analysis of the data obtained from the H-NMR spectrum and the 2D NMR experiments, showed that (98) was an isomer of (97), with different substitution of the subunits. Its absolute configuration was determined by its CD curve. The lingkages between the units were determined to be C3-0-C2 , C4-0-C3 and C6 -0-C2 , C7 -0-C3 , respectively. According to the data obtained, the structure of (98) is showed below, and the compound was called triscutin B, Fig. (54).
