| titleOfInvention | Method of preparing derivatives from usnic acid |
| abstract | The invention comprises addition products of usnic acid obtained by reacting usnic acid dissolved or suspended in an inert organic solvent with a quaternary ammonium base or a salt thereof, or with a quaternary ammonium base or a salt thereof and an amino-sugar. The usnic acid and the quaternary ammonium base or a salt thereof, or the quaternary ammonium b base or a salt thereof and an amino-sugar. The usnic acid and the quaternary ammonium base or a salt thereof, or the quaternary ammonium base or a salt thereof and the amino-sugar may be reacted in equimolecular quantities. Suitable quaternary ammonium salts are benzyldimethyl - (2 - [2 - (p - 1,1,3,3 - tetramethyl - butylphenoxy) - ethoxy] - ethyl) - ammonium chloride and (2 - [2 - (p - di - isobutylphenoxy) - ethoxy] - ethyl) - dimethylbenzyl - ammonium bromide. Suitable inert solvents are acetone, dioxane, ethanol, carbon tetrachloride, chloroform, methanol, a propyleneglycol, toluene or trichloroethylene. In the example an addition compound is prepared by reacting usnic acid, benzyldimethyl - (2 - [2 - (p - 1,1,3,3 - tetramethyl - butylphenoxy) - ethoxy] - ethyl - ammonium chloride and N-methyl-l-glucosamine. |
