  • Chiral heterogeneous catalyst for assymmetric nitroaldol reaction
    Patent number: 8557726
    Abstract: The present invention relates to the preparation of highly efficient chiral heterogeneous catalyst for asymmetric nitroaldol reaction, wherein Henry reactions of various aldehydes such as aromatic, aliphatic, ?,?-unsaturated aldehydes, alicyclic aldehydes and nitroalkenes were carried out to produce optically active ?-nitroalcohols in high yield, with moderate to excellent enantioselectivity (ee up to >99%) in presence of a base and an optically active chiral heterogeneous catalyst.
    Type: Grant
    Filed: October 11, 2010
    Date of Patent: October 15, 2013
    Assignee: Council of Scientific & Industrial Research
    Inventors: Sayed H. R. Abdi, Rukhsana I. Kureshy, Noor-Ui H. Khan, Hari C. Bajaj, Vishal J. Mayani, Arpan K. Shah
