Asymmetric Synthesis of Unusual Amino Acids: An Enantioselective Synthesis of the Four Isomers of D- and L-O-Methyl-2',β-Dimethyltyrosine

Article abstract of DOI:10.1016/S0040-4039(00)77626-X

The four individual isomers of D- and L-O-methyl-2',β-dimethyltyrosines have been synthesized in high optical purity.The evidence for asymmetric induction was confirmed by the X-ray analysis of one of the key intermediates.
