✦ Synopsis

m-hydroxy-u-oximinopropiophenone was hydrogenated by tritium gas in the presence of Pd on carbon catalyst. The crude product was chromatographed on a cation-exchange column. Two major peaks were obtained. Subsequent radio-paper chromatography revealed that these peaks were identical with metaraminol and a-methyl-m-tyramine respectively. When 3,4-dibenzyloxy-uoximinopropiophenone was used as starting material both erythro and threo u-methylnoradrenaline as well as a-methyldopamine

## Abstract Solid‐state NMR spectroscopy was applied to the analysis of melanins prepared by peroxidase‐H~2~O~2~ oxidation of dopamines specifically ^13^C labelled in the α‐ or β‐side chain positions. A surprisingly diverse pattern of signals indicated the presence of uncyclized dopamine and noradr
