Abstract
Procedure for obtaining the acid l-alpha- (3,4-dihydroxybencil) -alfa-hydrazinopropinoic. Consists of the following stages: 1. Reaction of l (-) - alpha-methyl-3,4-dihydroxyphenylalanin with cyanate, obtaining l-4- (3 (4-dihydroxybencil) -4-methyl-hydantoic or acid l-4 (3,4-dihydroxybencil) -4-methylthohhythantoic 2. Methylation of the obtained product, obtaining the acid l-4- (3,4-dimetoxibencil) -4-methythydentoic or l-4- (3,4-dimetoxibencil) -4-methyl-chlutantoic that in a third phase is transformed into acid l (alpha) - (3,4-dimetoxibencil-alpha-propionic hydrazino 4. Reconversion of metoxi groups by treatment with a hydracide obtaining the acid l-alpha- ( 3,4-dihydroxybencil) -alfa-hydrazinopropionic. (Machine-translation by Google Translate, not legally binding)
