  Novel Sirtuin Activating Compounds and Methods for Making the Same

  摘要：

  本发明涉及一种制备白藜芦醇、白藜芦醇酯和给定以下结构式的取代和未取代的stilbenes的方法；其中每个Y是—O或卤素，每个Z是—O或卤素，每个n和每个m独立地取值为0、1、2、3、4或5，每个A和每个B独立地从Pn、R或缺席中选择，每个V和每个W独立地从Pn、由（2）到（6）个碳原子的直链或支链烷基和由（3）到（8）个碳原子的环烷基、烷氧基、苯基、苄基或卤素中选择，R独立地从包括至少一个碳原子的烷基、芳基和芳基烷基的群体中选择，Pn是醇保护基和上述化合物的对映异构体。这些化合物是通过多步过程制备的，其中包括在碱存在下与苄基卤和苯乙烯偶联合成N-杂环碳型配体偶联。这些化合物在食品、化妆品和制药行业中显示出增强的稳定性。

  Synthesis of polyhydroxylated ester analogs of the stilbene resveratrol using decarbonylative Heck couplings

  摘要：

  Protected 3,5-hydroxy-benzoyl chlorides 3 were coupled with styrenes 4 to give hydroxylated stilbenes, analogs of resveratrol, an important antioxidant disease preventative agent isolated from grape skins and other dietary sources. Levulinate and chloroacetate protecting groups allowed for the selective production of mono- and di-acetate variations under palladium-N-heterocyclic carbene (NHC) catalyzed decarbonylative coupling conditions. Fluorinated analogs were also produced using Heck conditions with bromofluorobenzenes. Human HL-60 cell assays showed the 4'-acetoxy variant 11 to have improved activity (ED50 17 mu M) relative to resveratrol (24 mu M). (c) 2006 Published by Elsevier Ltd.

  The present invention includes methods for preparing resveratrol, resveratrol esters and substituted and unsubstituted stilbenes of the formula given below; where each Y is —O or halogen, each Z is —O or halogen, each n and each m is independently the value of 0, 1, 2, 3, 4 or 5, each A and each B is independently selected from P n , R or absent, each V and each W is independently selected from P n , straight or branched alkyl of from (2) to (6) carbon atoms and cycloalkyl of from (3) to (8) carbon atoms, alkoxy, phenyl, benzyl or halogen, R is independently selected from the group comprising alkyl with at least one carbon atom, aryl and aralkyl, P n is an alcohol protecting group and diastereoisomers of the foregoing. The compounds are made from a multi-step process including a N-heterocyclic carbon-type ligand coupling in the presence of a base with benzyol halide and styrene coupling partners. These compounds show increased stability for use in the food, cosmetic and pharmaceutical industries.
