  • Single pot process for the regioselective synthesis of neolignan framework asarones
    Patent number: 7872160
    Abstract: The present invention provides a single pot process for the regioselective synthesis of neolignan framework [3(R)-Ethyl-2(S)-methyl-3-(2?,4?,5?-trimethoxyphenyl)-1-(2?,4?,5?-trimethoxyphenyl)propane from toxic ?-isomer rich asarone using montmorillonite acidic clay by employing microwave organic reaction enhancement (MORE) chemistry. This may be useful as versatile synthetic protocol for the synthesis of a large number of lignan and neolignan frameworks.
    Type: Grant
