The cyclization of alkyllithium reagents onto methoxy alkenes has been investigated. The alkyllithium reagent was generated by reductive lithiation of an alkyl nitrile. In an unbiased substrate, a methoxy leaving group attached to a stereogenic secondary
Intramolecular S(N)2' cyclization of an alkyllithium species onto a methoxy allyl ether is syn selective.

The preference for syn- or anti-addition of an intramolecular S(N)2[prime or minute] cyclization of an alkyllithium species onto a methoxy allyl ether has been proven unequivocally to take place by a syn S(N)2[prime or minute] mechanism.
