Chemoenzymatic Synthesis of (S)-Hexafluoroleucine and (S)-Tetrafluoroleucine
摘要:
We have developed a short chemoenzymatic synthesis for both (S)-5,5,5,5',5',5'-hexafluoroleucine (Hfl) and (S)-5,5,5',5'-tetrafluoroleucine (Qfl) on gram scale. Qfl was incorporated into a peptide using standard solid-phase peptide synthesis protocols to measure its helix propensity. The helix propensity for Qfl is 0.68 kcal center dot mol(-1) more favorable compared to Hfl.
