[EN] PROCESSES FOR THE PREPARATION OF ORTHO-ALLYLATED HYDROXY PHENYL COMPOUNDS [FR] PROCÉDÉS DE PRÉPARATION DE COMPOSÉS HYDROXYPHÉNYLE ORTHO-ALLYLÉS
摘要:
The present application describes process for preparing an ortho-allylated hydroxy aryl compounds such as compounds of Formula (I) by reacting an allylic alcohol with a hydroxy aryl compound in the presence of aluminum compound selected from alumina and aluminum alkoxides and in a non-protic solvent wherein at least one carbon atom ortho to the hydroxy group in the hydroxy aryl compound is unsubstituted.

1,1-Dimethylallene reacts with phenolic substrates in the presence of catalytic amounts of platinum(II) complexes. A regiospecific C-alkenylation takes place, affording o-isopentenylphenols and 2,2-dimethylchromans. Possible reaction mechanisms are also discussed.
