Özet

Two δ-truxinic type dimers; compound 1, rel-(1β,2α)-di- (2-thienoyl)-rel-(3β,4α)-di-(4-methoxy)phenyleyelobutane and compound 2, rel-(1β,2α)-di-(2-thienoyl)-rel-(3β,4α) -di-(3,4-dimethoxy)phenyleyelobutane were synthesized stereoselectively in solution by the dimerization of two known methoxy derivatives of heteroaryl chalcones (2E)-1-(2-thienyl)-3-(4-methoxy)-phenylpropen-1-one (3) and (2E)-1-(2-thienyl)-3-(3,4-dimethoxy)-phenylpropen-1-one (4). Precursor chalcones and the dimeric products showed antioxidant activities of different extents with respect to individual compounds as well as to the antioxidant methods. © 2004 Elsevier B.V.
