PROCESSES FOR THE PREPARATION OF ORTHO-ALLYLATED HYDROXY ARYL COMPOUNDS

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).

gem-Diprenylation of Acylphloroglucinols by a Fungal Prenyltransferase of the Dimethylallyltryptophan Synthase Superfamily

Aspergillus terreus aromatic prenyltransferase (AtaPT) catalyzes predominantly C-monoprenylation of acylphloroglucinols in the presence of different prenyl diphosphates. With dimethylallyl diphosphate (DMAPP) as prenyl donor, gem-diprenylated products 1D3, 2D3, and 3D3 were also detected. High conversion of 1D1 to 1D3, 2D1 to 2D3, and 3D1 to 3D3 was demonstrated by incubation with AtaPT and DMAPP. The first example of gem-diprenylation by a member of the dimethylallyltryptophan synthase superfamily is provided.

Friedel-Crafts Alkylation of Acylphloroglucinols Catalyzed by a Fungal Indole Prenyltransferase

Naturally occurring prenylated acylphloroglucinol derivatives are plant metabolites with diverse biological and pharmacological activities. Prenylation of acylphloroglucinols plays an important role in the formation of these intriguing natural products and is catalyzed in plants by membrane-bound enzymes. In this study, we demonstrate the prenylation of such compounds by a soluble fungal prenyltransferase AnaPT involved in the biosynthesis of prenylated indole alkaloids. The observed activities of AnaPT toward these substrates are much higher than that of a microsomal fraction containing an overproduced prenyltransferase from the plant hop.
