(-)-DIPIVALOYL-L-TARTARIC ACID Chemical Properties,Usage,Production

Chemical Properties

white to light yellow crystal powde

Uses

(?)-O,O′-Di-pivaloyl-L-tartaric acid can be used:

As a chiral staple in the synthesis of helical π-conjugated cyclic nanocoils, which are used as nano springs, nano solenoids, and pressure sensors.
As an additive in the iridium-catalyzed C-H amidation reactions of arylphosphoryl compounds.

Application

(2R,3R)-Dipivaloyltartaric Acid is used as a chiral auxiliary for enantioselective protonation (deracemization) and asymmetric transformation; starting material for synthesis of chiral succinimides and polyhydroxy compounds.

Preparation

Preparative Method of (2R,3R)-Dipivaloyltartaric Acid: hydrolysis of the corresponding anhydride obtained by heating (2R,3R)-tartaric acid and pivaloyl chloride at 120-140 °C for 4 h.^[1] Drying: over P2O5 in vacuo, controlled by 1H NMR and optical rotations.

storage

(2R,3R)-Dipivaloyltartaric Acid anhydrous solid can be stored at rt in the absence of moisture. It is retrievable from its basic solution (10 % aq NaHCO3), after acidification (HCl), with a quantitative yield.2 On heating it transforms into an anhydride with elimination of one molecule of water.
