Literature References

Acyl anion equivalent, compare 1,3-Dithiane, A10505. Can be metallated, e.g. with n-BuLi. Dimetallation requires a metal complexing agent, e.g. TMEDA, allowing dialkylation: Tetrahedron Lett., 21, 4763 (1980).

The products of addition of the lithio-derivative to aldehydes and ketones undergo a pinacol-type rearrangement with CuOTf, with insertion of a one-carbon unit adjacent to the carbonyl group: J. Am. Chem. Soc., 97, 4749 (1975); see also: Org. Synth. Coll., 6, 737 (1988). An alternative method utilizes an alkyllithium to effect a carbenoid rearrangement, which has been applied to ring expansion: Tetrahedron Lett., 28, 20 (1987):
