Application
Dibenzoyl-L-tartaric acid may be used as a chiral resolving agent for the resolution of racemic Troger base. It may also be used as a ligand to synthesize chiral transition metal complexes, which have potential utility in organic asymmetric catalysis.

In a screening procedure a pink-colored yeast was isolated from enrichment cultures with (2R,3R)-(-)-di-O-benzoyl-tartrate (benzoyl-tartrate) as the sole carbon source. The organism saar1 was identified by morphological, physiological, and 18S ribosomal DNA/internal transcribed spacer analysis as Rhodotorula mucilaginosa, a basidiomycetous
