title: A synthesis of (R)-recifeiolide by the aid of biochemical reaction as the key-step.
abstract: (R)-Recifeiolide, a naturally occurring macrolactone, was synthesized in optically pure form by the aid of biocatalysts. Lipase-catalyzed lactonization of the racemic precursor afforded the desired compound with a concomitant kinetic resolution. The optically active acyclic precursor could be synthesized by the reduction of corresponding ketone with Pichia farinosa IAM 4682. The yeast reduction proceeded with the anti-Prelog rule, selecting si-face attack on the carbonyl group to give (R)-alcohol with > 95% e.e.
