Popis: | Asymmetric amination of 4-methoxyphenylacetone and its related compounds by microorganisms was investigated. Among 630 type culture strains, 4-methoxyphenylacetone-aminating ability was found inBrevibacterium, Chromobacterium, Flavobacterium, Mycobacterium, Pseudomonas, andSarcina spp. 4-Methoxyamphetamine produced by these microorganisms was the (S)-(+)-enantiomer.B. linens IFO 12141 was selected as the best strain. The optimum pH of amination was about 7.0, andl-alanine was the most effective aminov donor for the amination. By using this strain, 37.6 mM (S)-(+)-4-methoxyamphetamine was formed with a 94% conversion yield from 4-methoxyphenylacetone. As for substrate specificity,B. linens IFO 12141 catalysed amination of 3,4-dimethoxyphenylacetone and 4-(4-methoxyphenyl)-2-butanone, and formed the corresponding optically active amines. |
