The Z- and E-4,5-dimethoxy-2-prenyloxycinnamic acids (2 and 6), obtained by ring opening of 6,7-dimethoxycoumarin (1; scoparone) under different conditions followed by prenylation, undergo Claisen rearrangement to give scopoletin (3) together with suberosin (4) and 3-prenylscoparone (7), respectively.The steric and sustituent effects have been discussed.
