  Me3SI-mediated simple and efficient protocol for the chemoselective deprotection of acetyl groups has been developed via employing KMnO4 as an additive. This chemoselective deacetylation is amenable to a wide range of substrates, tolerating diverse and sensitive functional groups in carbohydrates, amino acids, natural products, heterocycles, and general scaffolds. The protocol is attractive because it uses

  Disclosed are improved methods for the synthesis of phospholipid ether analogs and alkyl phosphocholine analogs. The methods allow greater versatility of the reactants used and greater ease in synthesizing alkyl chains of varying length while affording reaction temperatures at room temperature or below. The methods disclosed herein provide reactants and conditions using alkyl halides and organozinc reagents and do not utilize Gringard reactions thus, allowing greater ease of their separation and purity of products. The PLE compounds synthesized by the methods disclosed herein can also be used for synthesizing high specific activity phospholipid ether (PLE) analogs, for use in treatment and diagnosis of cancer.

  Isosteric side chain analogs of 3a were synthesized and tested for inhibitory activivies towards 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) synthase and upon cholesterol production in Hep G2 cells and in mouse liver. It became clear that the lipophilic substituent on the aromatic ring and the terminal hydrophilic group in the side chain were important in the enhancement of activity. 4-[2-(3-n-Hexyloxyphanyl)ethyl]-3-hydroxymethyl-2-oxetanone (5a) showed equivalent inhibitory activity in vivo to that of 1233A.

  同位素侧链类似物3a被合成并测试了对3-羟基-3-甲基戊二酰辅酶A（HMG-CoA）合酶以及在Hep G2细胞和小鼠肝脏中胆固醇生成的抑制活性。结果表明，芳环上的亲脂性取代基和侧链末端的亲水性基团对活性的增强非常重要。4-[2-(3-正己氧基苯基)乙基]-3-羟甲基-2-氧杂环丁酮（5a）在体内的抑制活性与1233A相当。
