Asymmetric synthesis of febrifugine and isofebrifugine using yeast reduction
Abstract
The antimalarial agents febrifugine ((+)-1) and isofebrifugine ((+)-2) were asymmetrically synthesized from chiral piperidin-3-ol ((+)-4), which was prepared by the reductive dynamic optical resolution of the 3-piperidone derivatives ((±)-3) using baker’s yeast.
