Abstract:
Novel derivatives of 1-aminoindan and their salts are described. Optically active 1-aminoindan derivatives are prepared by reacting a N-benzyl analog of the desired compound with an enantiomer of mandelic acid. Parkinson's disease, dementia, epilepsy, convulsions, or seizures are treated by administering a compound of formula (I).

Further the use of novel salts in the preparation of the compound of formula- 1. The present invention also relates to the novel process for the preparation of the compound of formula- 1.
Abstract:
Methods and compositions are provided for synthesizing ionic liquids from lignin derived compounds comprising: contacting a starting material comprising lignin with a depolymerization agent to depolymerize the lignin and form a mixture of aldehyde containing compounds; contacting the mixture of aldehyde containing compounds with an amine under conditions suitable to convert the mixture of aldehyde containing compounds to a mixture of amine containing compounds; and contacting the mixture of amine containing compounds with an acid under conditions suitable to form an ammonium salt, thereby preparing the ionic liquid.
