A highly selective cleavage of prenyl ethers has been achieved in high yields using p-toluenesulfonic acid under extremely mild conditions. This method is compatible with a wide variety of functional groups such as methyl, benzyl, allyl ethers and benzyl, methyl, prenyl esters present in the molecules.

Hydroxychavicol (HC), which is obtained from the leaves of Piper betle LINN. (Piperaceae), inhibits xanthine oxidase (XO) with an IC50 value of 16.7μM, making it more potent than the clinically used allopurinol (IC50=30.7μM). Herein, a structure–activity relationship analysis of the polar part analogs of HC was conducted and an inhibitor was discovered with a potency 13 times that of HC. Kinetic studies have revealed that HC and its active analog inhibit XO in an uncompetitive manner. The binding structure prediction of these inhibitor molecules to the XO complex with xanthine suggested that both compounds (HC and its analog) could simultaneously form hydrogen bonds with xanthine and XO.
Oxidative cyclization of alkenoic acids promoted by AgOAc
Carrillo-Arcos, Ulises A.,Rojas-Ocampo, Jonathan,Porcel, Susana

Alkenoic acids derived from salicylic acid and analogues undergo an unexpected oxidative cyclization process triggered by AgOAc leading to 4H-benzo[d][1,3]dioxin-4-ones. The process is affected by the substitution on the aryl and the allyl units.
