Acid catalyzed stereoselective rearrangement and dimerization of flavenes: synthesis of dependensin

Appropriately substituted flavenes undergo stereoselective rearrangement and dimerization when treated with methanolic hydrochloric acid to give benzopyranobenzopyrans. A rationale for the rearrangement is proposed. This synthetic methodology has been used for a high yield synthesis of the natural product dependensin.

Synthesis of hydroxyflavanones from substituted acetophenones and benzaldehydes in the presence of silica gel, boric acid and piperidine

Direct synthesis of hydroxyflavanones from appropriately substituted acetophenones and benzaldehydes was achieved in the presence of boric acid, silica gel and piperidine. The formation of flavanones presumably involved the reaction between the acetopheno

Metabolism of 2',4,4'-Trihydroxychalcone in Amorpha fruticosa Seedlings; Structure and Role of Chalaurenol, a Novel Heterocyclic Enol Ether formed by Enzymic Oxidation

Amorpha fruticosa seedlings contain two enzymes capable of catalysing reactions of 2',4,4'-trihydroxychalcone.One is a chalcone-flavanone isomerase, which has been purified and occurs as two isozymes.More interestingly, the second is a peroxidase, which oxidises the chalcone (1; R1 = R2 = OH, R3 = H) to a novel labile quinol enol ether, chalaurenol (6), whose structure is established by chemical studies and X-ray diffraction of the 6-O-methyl ether (5).The possible origins and role of chalaurenol in plant metabolism are discussed.

HETEROCYCLES. XIX. REACTION OF 2'-HYDROXYCHALCONES WITH ALKALINE HYDROGEN PEROXIDE

Reaction of 2'-hydroxychalcones, which contain the hydroxyl and/or the methoxyl group at the 4- and 6'-positions, with alkaline hydrogen peroxide has been examined.It is observed that these substituents intricately influence the formation of the products.
