Abstract
Oxidn. of α-methyldopa Me ester leads to the aminochrome I, which, at neutral pH, spontaneously rearranges to give a relatively stable quinone-methide identified as II. This provides the first evidence for the postulated intermediacy of quinone-methides in the conversion of aminochromes to 5,6-dihydroxyindoles.File in questo prodotto:
