Jm. Mattalia et al., COMPLETE ANALYSIS OF THE H-1 AND C-13 NMR-SPECTRA OF 5-ISOPROPYLSULFONYL-2-NORBORNENES THROUGH THE APPLICATION OF 2-DIMENSIONAL NMR TECHNIQUES, Spectroscopy letters, 26(4), 1993, pp. 575-583
Total assignment of C-13 and H-1 NMR spectra of the 5-isopropylsulfony
l-2-norbornenes 2 was achieved using the concerted application of two-
dimensional homonuclear and heteronuclear chemical shift correlations.
The stereochemistry of both the diastereoisomers endo 2a and exo 2b h
ave been established using the magnitude of the proton coupling consta
nts.
