摘要：

The C-6-methylene protons in the internal glucosyl unit of panose, D-Glc-alpha(1 --> 6)-D-Glc-alpha(1 --> 4)-D-Glc(alpha,beta), were stereospecifically assigned. The assignment strategy involved the measurement of the long-range 3J(C-4, H-6R) and 3J(C4,H-6S) coupling constants for this residue in panose, with natural C-13 isotope abundance, using a newly designed C-13-filtered 1D TOCSY experiment.
