Nonenzymatic kinetic resolution of α-aryl substituted allylic alcohols catalyzed by acyl transfer catalyst Np-PIQ
摘要:
Chiral alpha-aryl substituted allylic alcohols are important versatile synthetic intermediates. We report here an effective nonenzymatic kinetic resolution of racemic alpha-aryl substituted allylic alcohols by introducing different aryl groups with acyl transfer catalyst Np-PIQ and propionic anhydride, providing moderate to good selectivity factors (S=12-37).
