39 - 055Claisen Rearrangement of Allylfluorovinyl Ethers. — Metalation ofallylic alcohols followed by coupling with the trifluorovinylsilane (II) generatesallylfluorovinyl ethers. These undergo diastereoselective Claisen rearrangementto yield α-fluoro β-substituted γ-unsaturated acids (III) after hydrolyticwork-up. — (TELLIER, F.; AUDOUIN, M.; BAUDRY, M.; SAUVETRE, R.;Tetrahedron Lett. 39 (1998) 28, 5041-5044; Unite Phytopharm.
