A series of bis(catechol) quaternary ammonium derivatives were designed and synthesized. We investigated their ability to cross-link DNA induced by tyrosinase and found that the o-quinone is key intermediate in the process by using the nucleophile 3-methy

PROCESS FOR PRODUCTION OF HYDROXYTYROSOL USING ORGANOMETALLIC COMPOUNDS
-
Page/Page column 15, (2012/02/02)
Disclosed is a process for the production of a 4-(2-hydroxyalkyl)-1,2-benzenediol, comprising the steps of (a) providing protected 1,2-benzenediol having the 1,2-hydroxyl groups protected, (b) halogenating the protected 1,2-benzenediol to obtain a protected 4-halo-1,2-benzenediol having the 1,2-hydroxyl groups protected, (c) reacting, in the presence of a metal or organometallic compound, the protected 4-halo-1,2-benzenediol to protected 4-(2-hydroxyalkyl)-1,2-benzenediol having the 1,2-hydroxyl groups protected, and (d) deprotecting the protected 4-(2-hydroxyalkyl)-1,2-benzenediol to obtain the 4-(2-hydroxyalkyl)-1,2-benzenediol. Also disclosed is the use of 1,2-benzenediol for the production of hydroxytyrosol.

The idea that foods consumed for pure pleasure could provide health benefits received much recognition in the recent years. Among these foods, cocoa and dark chocolate are particularly rich in procyanidins, one of the major dietary families of polyphenols. We developed the first asymmetric total synthesis of procyanidin B2 and applied it to the preparation of a regioselectively radiolabeled 14C-analogue, which will be used to strengthen our knowledge on the metabolism of procyanidins.

5,5′,6,6′-Tetrahydroxy-3,3′-biindolyl, the proposed structure of a phenolic antioxidant isolated from the red beetroot (Beta vulgaris), has been synthesised. The spectroscopic data of the synthetic material is not consistent with that reported for the natural product.
Enantiospecific synthesis of the antituberculosis marine sponge metabolite (+)-puupehenone. The arenol oxidative activation route.
Quideau, Stephane,Lebon, Marjolaine,Lamidey, Anne-Marie
, p. 3975 - 3978 (2007/10/03)
[formula: see text] The total synthesis of the marine sesquiterpene quinone (+)-puupehenone, a promising new antituberculosis agent, was achieved in 10 steps starting from commercially available (+)-sclareolide. The key feature of this synthesis is the construction of the heterocycle via an intramolecular attack of the terpenoid-derived C-8 oxygen function onto an oxidatively activated 1,2-dihydroxyphenyl unit.
