Chiral zeolitic material for synthesis of drugs and chiral chemicals

CSIC has developed a new chiral zeolitic material for the asymmetric synthesis of chiral chemical products. The material has a chiral structure (ITV) with a very high porosity (with extra-large pore openings, 4.3 x 19.3 Å) and active centers, which allows the catalytic enantioselective processing of large size molecules, reaching enantiomeric excesses in model reactions much [read more]
