Studies on Optically Active Amino Acids. X. Studies on α-Alkyl-α-amino Acids. V. Absolute Configuration of Biochemically Active (-)-α-Methyl-3, 4-dihydroxyphenylalanine

Abstract

The absolute configuration of biologically active (-)-α-methyl-3, 4-dihydroxyphenylalanine has been elucidated to be L-or S-configuration by the chemical correlation with (+)-α-methylaspartic acid, whose absolute configuration was confirmed in the previous report. Preriminary examinations using racemic compounds were also described.
