ABSTRACT:
Chalcone derivatives having at least one tetrahydropyranyloxy group is disclosed. Typically, the compounds are represented by general formula (I) ##STR1## wherein X and X' each represent a tetrahydropyranyl group, R and R', which are then same or different, each represent an alkyl group or a hydrogen atom, n and n' each are an integer of from 0 to 5, m and m' each are integers of from 0 to 5, provided that n+n' is 1 or more, and that n+m is an integer of from 0 to 5 and n'+m' is an integer of from 0 to 5. Also, disclosed are processes for producing the chalcone derivatives starting from acetophenone or its derivative and benzaldehyde or its derivative at least one of which has at least one tetrahydropyranyloxy group. Further, disclosed is 2,3,4,2',4'-pentahydroxychalcone.
