Two Routes to Chiral Dithianes, Useful Synthons for the Preparation of Functionalised Spiroketals

Article abstract of DOI:10.1016/S0040-4039(00)60180-6

Two routes are described leading to chiral precursors for the synthesis of new substituted spiroketals.The stabilities of the methoxymethyl, tert-butyldimethylsilyl and tert-butyldiphenylsilyl hydroxyl protecting groups were tested in these reaction seque
