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. The present application also includes compounds of Formula (I).

Methods are examined for the synthesis of 4-(1′-acetoxy) alkylcoumarins having hexasubstituted aromatic rings. This has led to synthesis of the three insecticidalcoumarinsmammeaE/BB, mammeaE/BA and surangin B.
The invention relates to novel acylphloroglucinols which have strong growth inhibitory effects on multi-drug resistant strains of bacteria, particularly MRSA. Typically the compounds have a terpene substituent, or a terpene-derived substituent. Methods of isolating the compounds from natural sources, and synthetic methods for forming the compounds are also provided.
