New compounds of alkylamides derived from α-amino acids were tested as corrosion inhibitors for carbon steel in an aqueous solution of hydrochloric acid. The chemical synthesis of these amides performed by aminolysis of α-amino acid methyl esters resulted in good yields. Electrochemical testing was...
Syntheses of various different low molecular weight amino acid derivatives such as N-ω-protected α,ω-diamino acids, amino acid alkyl esters, amino acid amides, amino acid hydroxamic acids, amino acid hydrazides,α-aminoacetophenones, hydantoic acids and α-isocyanatocarboxylic acid chlorides, ...
This review highlights the occurrence of the N-alkyl-α-amino acid motif and its role in nature, important applications towards human health and biocatalytic methods of preparation. Several enzyme classes that can be used to access chiral N-alkylated-α-amino acids and their substrate selectivities...
