Abstract

Structural elucidation of a malate‐aluminum(III) complex has been carried out using ^1^H and ^27^Al NMR spectroscopy. The ^1^H chemical shift perturbation clearly indicated the interaction between malate and Al(III) ion. The measurements of ^27^Al NMR and ^1^H^13^C HSQC spectra demonstrated that the major form of a complex comprised two equivalent malate ions and two unequivalent Al(III) ions. With this constraint, an equilibrium geometry of the complex was proposed by a semi‐empirical molecular orbital calculation. Copyright © 2007 John Wiley & Sons, Ltd.

Synthetic melatonin was iodinated by treatment with potassium iodide in the presence of an oxidizing agent, Iodo-Gen. The iodination products of melatonin were extracted with chloroform and separated by HPLC. The fraction showing immunoreactivity with respect to melatonin antisera was characterized

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
