Despite their complicated full name, these compounds are easily accessed and are often used in as chiral auxiliaries.〔Seebach, D.; Beck, A. K.; Heckel, A., "TADDOLs, their derivatives, and TADDOL analogs: versatile chiral auxiliaries", Angew. Chem., Int. Ed. 2001, 40, 92-138. 〕 TADDOLs consist of a dioxolane ring substituted with two mutually transoid diarylhydroxymethyl (Ar2COH) groups. They are derived from d,l-tartaric acid, an inexpensive C2-symmetric molecule. Condensation of dimethyl ester of d,l-tartaric acid with acetone gives the acetonide, a particular kind of dioxalane. The ester groups are susceptible to reaction with aryl Grignard reagents, leading after hydrolysis to the diol.〔Albert K.
