Ring opening alkylation of cyclic ethers with α-halogenoalkyllithiums in the presence of boron trifluoride–diethyl ether
Abstract
It is demonstrated for the first time that α-halogenoalkyllithium reagents can be utilized for ring opening alkylation of various oxiranes, oxtane and oxolane (THF) in the presence of boron trifluoride–diethyl ether at low temperatures.
