HOHAHA). The stereochemistry of pyranosldes was assigned from 34< h coupling constant values determined from these experiments. The 13C spectrum was assigned by 1H-detected heteronuciear multiple-quantum correlation (1H [13C] HMQC) and by the hybrid method of HMQC-COSY. The glycosldlc linkage positions of the polymer were determined by 1H-detected multiple-bond correlation (1H [13C] HMBC) and by 2D-NOESY spectra. The position of the phosphodiester linkage was determined by splitting observed In the 13C resonances due to 31P couplings leading to the overall structure given In Chart I.
