  • Substituted cyclohexane-1, 3-dione compounds, process for preparation thereof and its applications
    Patent number: 8916723
    Abstract: A regio-selective and consecutive Michael-Claisen process has been developed for substituted cyclohexane-1,3-dione synthesis started from unsubstituted or substituted acetone and ?,?-unsaturated esters. Substituted cyclohexane-1,3-diones are the basic unit found in several natural products, bioactive alkaloids and acridine dione type heterocycles, polyphenols, and unnatural amino acid synthesis. Most of the potent herbicidal and pesticidal active molecules contain cyclohexane-1,3-dione derivatives. Such an important intermediate synthesis using a facile, atom economy and one-pot process is a demandable area in organic synthesis.
    Type: Grant
