TADDOL

The chiral auxiliaries TADDOLs (α,α,α,α-tetraaryl-1,3-dioxolane-4,5- dimethanols) developed by Seebach's group have found numerous applications in asymmetric synthesis ranging from utilization as stoichiometric chiral reagents or in Lewis acid mediated reactions, to roles in catalytic hydrogenation and stereoregular metathesis polymerization.

Chiral Diols

Apart from numerous examples using TADDOLs in metal-catalyzed asymmetric reactions, Rawal recently reported that TADDOLs could be used as Brønsted acid organocatalysts in highly stereoselective hetero-Diels–Alder reactions.
