A one-step preparation of 1,1-dimethylallyl (DMA) esters was optimized for the C-terminal protection of a range of Fmoc-protected amino acids. This preparation is not sensitive to the scale of reaction and affords the corresponding DMA esters in 70–99% yield with high regioselectivity. Additionally, these DMA-protected amino acids were used with the backbone amide linker (BAL) of Albericio and Barany
