formulated for the selective etherification of secondary alcohols catalyzed by NNN pincer-ruthenium(II) carbonyl complexes based on bis(imino)pyridine ligands in the presence of molecular oxygen under solvent-free and base-free conditions at 140 °C. Under these conditions, very high yields (up to 92%, ca. 6133 TON) of the corresponding ethers are obtained at a very low catalyst loading (ca. 0.015 mol%)

Acetals 3 and 4 of alkylthienylcarbinols 1 were prepared using an enantiomerically pure lactol 2. In the key step these compounds were desulfurized. After deprotection the target compounds 7 and ent-7 were obtained.
