N-Methyl amino acids occur in many natural products. Experimental strategies are presented for a unified approach to the synthesis of N-methyl derivatives through 5-oxazolidinones of the 20 common L-amino acids. The amino acids with reactive side chains that required protecting groups or devoted syntheses for side chain construction for N-methylation to proceed included serine, threonine, tyrosine, cysteine, methionine, tryptophan, asparagine, histidine, and arginine. The studies have provided improved methods for the preparation of N-methyl serine, threonine, and tyrosine. All 20 of the common L-amino acids are now available in suitable forms for solid or solution-phase peptide synthesis.

Synthesis of Peptides Containing S-(N-Alkylcarbamoyl)cysteine Residues, Metabolites of N-Alkylformamides in Rodents and in Humans

Hydrochloride salts of S-(N-methylcarbamoyl), S-(N-ethylcarbamoyl), and S-(N,N-dimethylcarbamoyl) derivatives of cysteine, N-acetylcysteine, and cysteinylglycine have been prepared.S-(N-Methylcarbamoyl)glutathione hydrochloride has also been synthesized.Protecting groups for amino and carboxylic acid functions were selected for their ability to solubilize the peptides in dichloromethane in which solvent the thiols were treated with alkyl isocyanates and with N,N-dimethylcarbamoyl chloride.Removal of S-(amidomethyl) protecting groups using mercury(II) acetate was found to cause some loss of N-(tert-butoxycarbonyl) groups.Elimination of disulfide was evident during coupling of disulfide derivatives of cysteine using mixed anhydride methods but not with a carbodiimide coupling agent.Mixed disulfide protections were reductively cleaved by propane-1,3-dithiol.Many of the deprotected S-carbamoyl amino acids and peptides are metabolites of the corresponding N-alkylformamides in rodents and in humans.
