An efficient and convenient protocol has been developed for ether bond formation in mild conditions. A mixture of primary/secondary ester and allylic/benzylic halide in tetrahydrofuran was treated with KOtBu at room temperature to give ether in high yield. This step economic method enabled direct alkylation of the acyl group masked O-nucleophiles. Application of this method in carbohydrate synthesis was feasible and chemo-selectivity can be achieved.

The palladium-catalyzed coupling of alkynes with alcohols and carboxylic acids to give allylic ethers and esters has been achieved. With phenols, these conditions furnish the C-alkylation products.

, p. 619 - 622 (2007/10/02)
Bu3-SnH-HMPA combined system is an efficient reagent for the reduction of aldehydes.The reaction proceeds in good yields, and chemoselective carbonyl reduction is achieved for the substrate which includes another reducible group.Moreover, the intermediate, tin alkoxide, undergoes further reaction such as the preparation of ethers and heterocyclic compounds in the one pot procedure.
