Abstract:
The 1 H, 13 C, and 31 P NMR signals of six chiral phospholene chalcogenides (X = O, S, Se) are duplicated in the presence of one mole equivalent of the chiral auxiliary Rh 2 [( R )‐MTPA] 4 (diastereomeric dispersion Δν; in Hz). The samples were investigated as nonracemic mixtures of enantiomers with known absolute configurations so that signs can be attributed to the Δν‐values and each signal set can be assigned to the respective enantiomer. The signs are uniform — in particular those of 1 H nuclei — and nearly independent of the nature of the chalcogen atom. Thus, if the absolute configuration of one compound is known, it is possible to derive absolute configurations in the whole series (correlation method). Chirality, 2006. © 2006 Wiley‐Liss, Inc.
