Direc T Facile Tetrahydrofuranylation of Alcohols inp-TsCl/NaH/THF System
摘要:
Several alcohols were converted in excellent yields into their 2-tetrahydrofuranyl-ethers in the presence of p-TsCl and NaH in THF under mild conditions. A radical process was proposed.

The reaction of dimethylboronbromide with THP and THF ethers was studied. Under conditions of kinetic control, these reactions proceed by selective cleavage of the ring carbon—oxygen bond to give acyclic α-bromo ethers. Treatment of these intermediates with a variety of nucleophiles gives ring-opened products.
