Abstract
A series of trans-3,4-dibenzyltetrahydrofurans has been synthesised and sub jected to oxidative cyclisation using ruthenium tetra(trifluoroacetate), af fording dibenzocyclooctadiene lignans belonging to the isostegane series, i n high yields. Since no evidence was found for the formation of the corresp onding stegane isomers it is assumed that the reactions proceed with comple te diastereoselectivity. (C) 2001 Elsevier Science Ltd.
