## Abstract The N(CH~3~)~3~ resonance of ergothioneine in ^1^H spinβecho Fourier transform (SEFT) NMR spectra of red blood cells is usually a large singlet and it has been common practice to use this apparently unchanging resonance as an intensity reference. Recently, Reglinski __et al__. (Magn. Re

It was found that the oxirane ring is a functional group amenable to chiral discrimination by dirhodium-MTPA complexes. Considerable signal shifts up to 0.7 ppm are observed for 1 H nuclei close to the rhodium atoms in the complex. In analogy to previously reported olefins, this method appears to be
The 1H NMR spectra of a variety of chiral racemic nitriles were recorded in in the absence CDCl 3 and presence of dirhodium tetra-(R)-a-methoxy-a-(triΓuoromethyl)phenylacetate MTPA 4 MosherΓs [Rh 2 (MTPA) 4 ; acid]. Moderate 1H signal shifts but clear diastereomeric dispersions due to complexation w
