  Discovery of a novel EP2/EP4 dual agonist with high subtype-selectivity

  摘要：

  A series of gamma-lactam prostaglandin E(1) analogs bearing a 16-phenyl moiety in the omega-chain and aryl moiety in the alpha-chain were synthesized and biologically evaluated. Among the tested compounds, gamma-lactam PGE analog 3 designed as a structural hybrid of 1 and 2 was discovered as the most optimized EP2/EP4 dual agonist with excellent subtype-selectivity (K(i) values: mEP2 = 9.3 nM, mEP4 = 0.41 nM). A structure-activity relationship study is presented. (C) 2011 Elsevier Ltd. All rights reserved.

  Elimination reactions of terminal .beta.-oxy selenoxides. Synthesis of aryl and vinyl enol ethers and of furans, oxazoles, and thiazoles

  摘要：

  Elimination reactions of terminal selenoxides holding an alkoxy group in the beta position, RCH-(OR)CH2SeOPh, are usually difficult and can give rise to complex reaction mixtures. We report that these reactions take place more easily whenever the oxygen atom is linked to an unsaturated group (-CH=CHR, -Ar, -CR=O, -CH=NR). These selenoxides are easily available, and the elimination reaction was employed to effect useful syntheses of both open-chain and cyclic aryl and vinyl enol ethers. Moreover, by simple isomerization with acids or bases the cyclic derivatives can be transformed into the corresponding furans. The same procedure has been employed to synthesize substituted oxazoles and thiazoles also.

  the construction of tetraalkyl furans remains non‐trivial. The prevalence of alkyl groups in bioactive furan natural products, combined with the desirable bioactivities of tetraalkyl furans, calls for a general synthetic protocol for polyalkyl furans. This paper describes a Michael–Heck approach, using sequential phosphine‐palladium catalysis, for the preparation of various polyalkyl furans from readily

  多烷基呋喃在自然界中广泛存在，通常发挥重要的生物学作用。尽管合成四取代呋喃的方法有很多，但四烷基呋喃的构建仍然很重要。生物活性呋喃天然产物中烷基的普遍存在，加上四烷基呋喃所需的生物活性，需要一种多烷基呋喃的通用合成方案。本文描述了一种 Michael-Heck 方法，使用顺序膦-钯催化，从容易获得的前体制备各种聚烷基呋喃。该方法的多功能性通过属于不同类别的九种不同的多烷基化呋喃天然产物（即呋喃萜玫瑰呋喃、倍半糖呋喃和米卡尼呋喃）的全合成来说明；海洋天然产物plakorsin A、B、D和plakorsin D甲酯；以及呋喃脂肪酸3D5和氢木霉素。
