Literature References

Alkylation of the dilithio-derivative leads to higher 2-alkynoic acids. Reaction with epoxides, partial reduction (Lindlar) of the triple bond and cyclization has been used in the synthesis of unsaturated lactones: Tetrahedron Lett., 2615 (1974); J. Org. Chem., 40, 1610 (1975).
