| titleOfInvention | Chalcone derivatives and process for producing the same |
| abstract | Chalcone derivatives having at least one ntetrahydropyranyloxy group is disclosed. Typically, the ncompounds are represented by general formula (I) n nwherein X and X′ each represent a tetrahydropyranyl group, nR and R′, which are the same or different, each represent nan alkyl group or a hydrogen atom, n and n ′ each are an ninteger of from 0 to 5, m and m ′ each are integers of from n0 to 5, provided that n + n ′ is 1 or more, and that n + n m nis an integer of from 0 to 5 and n ′ + m ′.is an integer of nfrom 0 to 5. Also, disclosed are processes for producing nthe chalcone derivatives starting from acetophenone or its nderivative and benzaldehyde or its derivative at least one nof which has at least one tetrahydropyranyloxy group. nFurther, disclosed is 2,3,4,2′,4′-pentahydroxychalcone. |
