Abstract

We report a new reaction for the direct construction of O,S-acetals, key intermediates in the assembly of fused polycyclic ethers. α- Fluorosulfides and secondary alcohols were coupled by the action of Yb(OTf) ₃ to generate O,S-acetals in high yield. The neutral and selective nature of the reaction should be useful for synthesizing natural and artificial polyethers with multisensitive functionalities.
