white to almost white cryst. low melting solid | [Uses]
(3aR,7aS)-rel-Hexahydro-1,3-isobenzofurandione is a reagent used in the synthesis of Pregabalin (P704800), a GABA analogue used as an anticonvulsant. Also used to prepare P2X7 receptor antagonists. | [Purification Methods]
It has been obtained by heating the trans-acid or anhydride at 200o. Crystallise it from *C6H6/Et2O or distil it. [Kohler & Jansen J Am Chem Soc 60 2145
