  Structure-activity relationships in prazosin-related compounds. Effect of replacing a piperazine ring with an alkanediamine moiety on .alpha.1-adrenoreceptor blocking activity

  摘要：

  Several prazosin-related compounds were synthesized in which the piperazine ring of prazosin (1) was replaced by an alkanediamine chain and were evaluated for their blocking activity on alpha 1- and alpha 2-adrenoreceptors in isolated rat vas deferens. All the compounds investigated proved highly selective toward the alpha 1-adrenoreceptor owing to a very low affinity for alpha 2-adrenoreceptors. Furthermore, compounds 2, 9, and 13 were also investigated in vivo to determine their hypotensive effect on anesthetized rats, which were compared with that of prazosin (1). It was confirmed that the piperazine moiety of 1 is not essential for potency. However, optimum activity depends on two parameters: carbon-chain length of the alkanediamine moiety and N-methylation of both the amide and the 2-amino functions. In the desmethyl series, optimum activity was associated with the lower homologues (2-4) bearing a chain of two to four methylenes whereas in the N,N'-dimethyl series peak potency was observed with a six-carbon chain as in 13. Compound 13 proved the most active of the series and was more potent than prazosin (1) in both in vivo and in vitro assays. It is hypothesized that the alpha 1-adrenoreceptor incorporates a lipophilic area that is located between the binding sites for the quinazoline and the furoyl moieties and is able to accommodate a polymethylene chain.

  通过环化/扩环级联反应合成大环和中型环的模块化策略

  摘要：

  大环和中型环在许多科学领域和技术中都很重要，但使用现有方法很难制造，尤其是大规模制造。本文概述了一种策略，通过该策略可以使用环化/扩环（CRE）级联反应来制备官能化大环和中等大小的环，而不需要采用高稀释条件。 CRE 级联反应专门通过动力学有利的 5-7 元环环化步骤进行操作；这意味着避免了通常与经典的端到端大环化反应相关的问题。已经开发出一种模块化合成方法，以促进所需线性前体的简单组装，然后可以使用九种 CRE 方案之一将其转化为极其广泛的官能化大环化合物和中等大小的环。

• Continuous Chemoselective Methylation of Functionalized Amines and Diols with Supercritical Methanol over Solid Acid and Acid−Base Bifunctional Catalysts

  日期：2004.6.1

  bifunctional catalysts (Cs-P-Si mixed oxide and gamma-alumina) was investigated in a continuous-flow, fixed-bed reactor. The use of scCH(3)OH in the reaction of 2-aminoethanol with methanol (amine/CH(3)OH = 1/10.8) over the solid catalysts led to a significant improvement in the chemoselectivity of the N-methylation. Among the catalysts examined, the Cs-P-Si mixed oxide provided the most efficient catalyst

  传统固体酸（H-丝光沸石、β-沸石、无定形二氧化硅-氧化铝）和酸碱双功能催化剂（Cs-P-Si）促进双官能化胺与超临界甲醇（scCH（3）OH）的选择性 N-甲基化混合氧化物和γ-氧化铝）在连续流动的固定床反应器中进行了研究。在 2-氨基乙醇与甲醇（胺/CH(3)OH = 1/10.8）在固体催化剂上的反应中使用 scCH(3)OH 导致 N-甲基化的化学选择性显着提高。在所检测的催化剂中，Cs-P-Si 混合氧化物在 300 摄氏度和 8.2 MPa 条件下的选择性和反应性方面提供了最有效的催化剂性能；产物中的 N-甲基化选择性在 86% 转化率下达到 94%。该选择性甲基化已成功应用于N-甲基化氨基醇和二胺以及O-甲基化乙二醇的合成。值得注意的是，乙氧基乙胺的反应性较低，这表明氨基醇的羟基是决定高反应性和选择性的关键结构因素，这可能是因为另一个末端（羟基基团）对催化剂表面的束缚效应。Cs-P-Si

  Conjugates derived from non-steroidal anti-inflammatory drugs (NSAIDs) and methods of use thereof are disclosed, useful for, inter alia, identifying and localizing the site of pathology and/or inflammation responsible for the sensation of pain in a patient; for identifying the sites of primary, secondary, benign, or malignant tumors; and for diagnosing infection or confirming or ruling out suspected infection. The NSAID-based conjugates contain an imaging moiety. The conjugates concentrate at sites of increased cyclooxygenase expression, thus revealing the sites of increased prostaglandin production, which is correlated with pain and inflammation, and correlated with tumor presence and/or location. Identifying areas of increased COX expressing can also aid in screening for infections.

  ethyl ketone enolates have been developed. The addition of enoxy(trichlorosilanes) (trichlorosilyl enolates) to aldehydes proceeds with good yields in the presence of catalytic amounts of chiral phosphoramides. The reaction of Z-trichlorosilyl enolates to aryl aldehydes affords aldol products with good to excellent diastereo- and enantioselectivities. Phosphoramide-catalyzed aldol additions lacked
