  Structure–activity relationships of 1′S-1′-acetoxychavicol acetate for inhibitory effect on NO production in lipopolysaccharide-activated mouse peritoneal macrophages

  摘要：

  1'S-1'-Acetoxychavicol acetate from the rhizomes of Alpinia galanga inhibited nitric oxide (NO) production in lipopolysaccharide-activated mouse peritoneal macrophages with an IC50 value of 2.3 mu M. To clarify the structure-activity relationship of 1'S-1'-acetoxychavicol acetate, various natural and synthetic phenylpropanoids and synthetic phenylbutanoids were examined, and the following structural requirements were clarified. (1) The para or ortho substitution of the acetoxyl and 1-acetoxypropenyl groups at the benzene ring was essential. (2) The S configuration of the 1'-acetoxyl group was preferable. (3) The presence of the 3-methoxyl group and disappearance of the 2'-3' double bond by hydrogenation reduced the activity. (4) The substitution of acetyl groups with propionyl or methyl groups reduced the activity. (5) Lengthening of the carbon chain between the 1'- and 2'-positions reduced the activity.

• Oxalic Acid-catalyzed Reaction of Alcohols with NaSCN: The Effects of Additives NaI and I₂
  作者：Hideyoshi Miyake、Yuichi Nakao、Mitsuru Sasaki

  DOI：10.1246/cl.2006.1262

  日期：2006.11

  Oxalic acid-mediated conversion of alcohols to thiocyante and/or isothiocyanate is described. Aliphatic tertiary alcohols give isothiocyanate by the reaction with NaSCN in the presence of I2, whereas they give thiocyanate without it.

• A molybdenum based metallomicellar catalyst for controlled and chemoselective oxidation of activated alcohols in aqueous medium
  作者：Prabaharan Thiruvengetam、Rajan Deepan Chakravarthy、Dillip Kumar Chand

  日期：2019.8

  A surfactant based oxodiperoxo molybdenum complex, which could activate molecular oxygen, has been employed as a catalyst for controlled oxidation of benzylic alcohols to corresponding carbonyls. The oxidation reactions were carried out under aqueous environment, however, in the absence of any extraneous base or co-catalyst. Sensitive/oxidizable functional groups like cyano, sulfide, hydroxyl, aryl-hydroxyl

  基于表面活性剂的氧二过氧钼络合物可以活化分子氧，已被用作催化剂，以控制苄基醇氧化为相应的羰基。氧化反应在水性环境下进行，但是在没有任何无关的碱或助催化剂的情况下进行。在转化过程中可以耐受敏感/可氧化的官能团，例如氰基，硫化物，羟基，芳基-羟基，烯烃（内部/末端），炔烃（内部/末端）和乙缩醛。这种选择性归因于催化剂的温和性质。该方法还可以扩大规模以用于多克合成，并且该方案很可能会得到实际应用，因为它需要廉价的可回收催化剂和易于获得的氧化剂（在绿色条件下）。
