1,4-Addition of the lithiated derivatives of the 1,3-dithiane and 2-phenyl-1,3-dithiane on α-unsaturated aldehydes is performed in THF-HMPA ; this reaction could be an interesting way to δ-carbonyl aldehydes.

A de novo synthesis of substituted pyridines is described that proceeds through nucleophilic addition of a dithiane anion to an α,β-unsaturated carbonyl followed by metallacycle-mediated union of the resulting allylicalcohol with preformed trimethylsilane-imines (generated in situ by the low-temperature reaction of lithium hexamethyldisilazide with an aldehyde) and Ag(I)- or Hg(II)-mediated ring closure
