introduction | Fmoc-D-leucine is white to off-white crystalline powder, which is the N-fmoc protected form of D-leucine. D-leucine, an unnatural isomer of L-leucine, acts as a self-inhibitor of Streptococcus lactis in culture. D-leucine causes analgesia in humans and also exhibits inhibitory activity in bacterial cell culture. |
Synthesis method | In the presence of alkali, 9-fluorenomethoxycarbonyl chloride reacts with leucine to obtain FMOC-D-leucine. This method is simple to operate, The method of preparing FMOC-D-leucine with mild reaction conditions, high yield and wide applicability. The synthesis reaction formula of FMOC-D-leucine is as follows: |
