  A new synthesis of 4′-resveratrol esters and evaluation of the potential for anti-depressant activity

  摘要：

  The 4'-ester analog of the disease preventative resveratrol 1 (RV), 4'-acetyl-RV 2 along with 4'-pivaloate 13 and benzoate 14 RV were synthesized. The previously developed palladium catalyzed decarbonylative Heck coupling was used to assemble the stilbene core together with 3,5-dibenzyl protected phenol intermediates that allowed for efficient coupling and deprotection using boron trifiuoride etherate. Studies with Long-Evans rats were performed to establish safety, toxicity, and behavioral parameters. In addition, the Porsalt forced-swim test was used to demonstrate anti-depressant activity.

• Selective esterification of the polyphenol resveratrol at the 4′-position

  Selective esterification of the polyphenol resveratrol was performed under thermodynamic conditions using NaH and acid anhydrides to directly access 4 '-esters. Standard conditions with acetyl chloride and pyridine showed poor selectivity, favoring esterification at the 3-position. The extended 4 '-phenolate anion is generated in preference to the 3-phenolate under the new anhydride-sodium hydride-DMSO conditions. Acylation occurs to access the 4 '-ester products with modest selectivity and yield with minimal formation of the 3-monoester, 3,5-diester, and triester products. (C) 2013 Elsevier Ltd.
