Literature References

Alkylation of the anion provides a route to ɑ-keto acids (by dethioketalization with NBS), or to substituted acetic acids (by desulfurization): J. Org. Chem., 37, 505 (1972). For phase-transfer alkylation using allylic bromides, see: Liebigs Ann. Chem., 1589 (1982). With crotyl bromide, approx. 95% allylic rearrangement occurs.

The lithiated derivative undergoes 1,4- (Michael) addition to a variety of ɑß-unsaturated compounds. However, the Mg derivative prepared by metallation with an alkylmagnesium halide gives an allylic alcohol by 1,2-addition: Chem. Ber., 114, 2924 (1981).
