Abstract :
1-Ethenylcyclopropyl sulfonate underwent electrophilic gamma- and α-substitutions by the carbonyls of naturally occurring biphenyls derived from vanillin and acetovanillone, in the presence ofpalladium(0) and diethylzinc, to provide regioisomeric 5,5’-di(3-cyclopropylidene-1-hydroxypropyl)biphenyls and 5,5’-di[1-(1-ethenylcyclopropyl)-1-hydroxymethyl] biphenyls of biological interest.
