Phase Diagrams for Mixtures of (S)-1-Phenylethylammonium (S)-Mandelate and (R)-1-Phenylethylammonium (S)-Mandelate.

Supramolecular structures of 1-phenylethylammonium tartrates.

The structures of six 1-phenylethylammonium tartrates have been determined and in each of them a distinctive hydrogen-bonded anion substructure can be identified. (S)-1-Phenylethylammonium (R,R)-hydrogen tartrate [(I), P21, Z'=1] contains anion sheets built from a single type of R4(4)(22) ring with cations pendent, via three N-H...O hydrogen bonds, from just one face of the sheet. (S)-1-Phenyle...

Stereoselective biotransformation of racemic mandelic acid using immobilized laccase and (S)-mandelate dehydrogenase

OBJECTIVES (S)-Mandelate dehydrogenase (SMDH) and laccase were immobilized on chitosan. The bi-enzymatic system with immobilized SMDH and immobilized laccase was taken to catalyze the stereoselective transformation of racemic mandelic acid and (R)-mandelic acid was obtained from its racemic mixture. RESULTS Characteristics of the immobilized enzymes were valuated. The optimum pH and temperatu...
