A synthesis for the recently identified, widespread bacterial natural product classes of dialkylresorcinols and cyclohexanediones was developed. The synthesis route is similar to the biosynthesis route in that the formation of the cyclohexanedione ring results from two parts, as exemplified by the synthesis of the multifunctional isopropylstilbenes identified in Photorhabdus luminescens. Testing of
The present invention provides processes for the preparation of 3, 5-Dihydroxy-4-isopropyl-trans-stilbene or a salt or solvate thereof and novel intermediates used therein. In some embodiments the 3, 5-Dihydroxy-4-isopropyl-trans-stilbene is prepared from (E)-2-chloro-2-isopropyl-5-styrylcyclohexane-1,3-dione. Also disclosed are crystal forms of 3, 5-Dihydroxy-4-isopropyl-trans-stilbene or a salt or solvate thereof and pharmaceutical compositions comprising same.
