environmentally friendly synthesis of Fmoc-N-methyl α- and β-amino acids from the corresponding Fmoc-amino acid, via intermediate oxazolidinones/oxazinanones, has been developed. Microwave heating for 3 min was required for the synthesis of the oxazinanones, while their Lewis acid catalyzed reductive opening only needed 1 min for completion. Hence, Fmoc-N-methyl-amino acids, suitable for, for example
