An enzymatic system for the synthesis of N-methyl-l-phenylalanine from phenylpyruvic acid and methylamine with a novel enzyme, N-methyl-l-amino acid dehydrogenase from Pseudomonas putida ATCC12633, using NADP+ and glucose dehydrogenase from Bacillus subtilis as a co-factor-recycling system is described. Analysis of the product on a laboratory preparative scale process revealed N-methyl-l-phenylalanine in 98% yield and over 99% ee. N-Methyl-l-phenylalanine can be used as chiral building blocks for the synthesis of several products with pharmacological activity.

Paragraph 0042; 0043, (2017/08/29)
The invention belongs to the field of medicine synthesis, relates to a preparation method of N-methylamino acid with optical configurations and in particular relates to a preparation method of N-methylamino acid with an R configuration and an S configuration. The preparation method is shown in the description. According to the preparation method provided by the invention, the configurations of reactants are transformed to obtain the N-methylamino acid with corresponding opposite configurations, and the preparation method is suitable for commercial scale production.

A range of oxazolidinones derived from N-carbamoyl α-amino acids were prepared by an efficient method as key intermediates in the synthesis of N-methyl amino acids and peptides. The method was readily applied to most α-amino acids except those with basic side chains. The oxazolidinones were converted by reductive cleavage into N-methyl α-amino acids. CSIRO 2000.
