Substitution of one or both TADDOL OH groups by other functional groups X, Y is key to new applications of this cheap chiral auxiliary, The Appel reaction and treatment with SOCl2 provide the mono and dichlorides, respectively. The chlorides are, in turn, replaced by various nucleophiles, and further modifications give a large variety of derivatives, including mono- and ditritylated dioxolanes. The new compounds-available in either enantiomeric form-are ready to be used in enantioselective synthesis and as dopants in liquid crystals.
