Thallium(III) trifluoroacetate has been shown to cleave dithianes which contain hydroxy functions that other reagents fail.Hydrolysis of a direct precursor of yashabushiketol led to tetrahydro-γ-pyrones, however.
A convenient preparation of symmetrical and unsymmetrical 1,2-diketones: Application to fluorinated phenytoin synthesis

1,2-Diketones are efficiently produced in two steps by reaction of aldehydes with anions derived from 2-substituted dithianes followed by treatment of the resulting alcoholis with NBS in aqueous acetone; phenytoin derivatives were prepared from these diketones by a standard method involving treatment with urea and potassium hydroxide under reflux.
