| titleOfInvention | Single step microwave induced process for the preparation of substituted stilbenes and its analogs |
| abstract | The present invention relates to a single step, microwave induced process for the preparation of substituted stilbenes and its analogs. Particularly, provides a method for the preparation of commercially important 2- or 4-hydroxy substituted stilbenes in one pot utilizing cheaper substrates in the form of 2- or 4-hydroxy substituted arylaldehyde and/or phenylacetic acids as well as regents in the form of base such as collidine, triethylamine, pyridine, piperidine, sodium acetate, ammonium acetate, imidazole, methyl imidazoles and the like and/or acid such as formic acid, acetic acid, propionic acid and the like for a reaction time varying from 1 min-16 hrs depending upon microwave or conventional heating, without using decarboxylating agents with yield varying from 37-66% depending upon the base and/or acid, solvent and substrate used. It is important to mention that the presence of hydroxy substitution at 2- or 4-position of arylaldehyde and/or aryl acetic acid is essential requirements towards formation of stilbenes in one step. |
