Enantioselective Synthesis of a Fluorinated Analogue of the Orsellinic Acid-Type Twelve-Membered Lactone Lasiodiplodin
摘要:
The chemoenzymatic synthesis of the racemate and the one enantiomer of the fluorinated analogue 8 of the natural cyclooxygenase inhibitor lasiodiplodin is decribed. A lipase-mediated deracemization of the fluorohydrin 18 provided the chiral, nonracemic building block for the enantioselective synthesis of the title compound. The key step was the formation of the 12-membered lactone by a ring-closing metathesis.
