Stereospecific assignment of exocyclic methylene protons in panose by 13C-filtered 1D TOCSY

The C‐6‐methylene protons in the internal glucosyl unit of panose, D‐Glc‐α(1 → 6)‐D‐Glc‐α(1 → 4)‐D‐Glc(α,β), were stereospecifically assigned. The assignment strategy involved the measurement of the long‐range 3J(C‐4, H‐6R) and 3J(C‐4,H‐6S) coupling constants for this residue in panose, with natural...

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