  Amidine−Oximes: Reactivators for Organophosphate Exposure

  摘要：

  A new class of amidine-oxime reactivators of organophosphate (OP)-inhibited cholinesterases (ChE) were designed, synthesized, and tested. These compounds represent a novel group of oximes with enhanced capabilities of crossing the blood-brain barrier. Lack of brain penetration is a major limitation for currently used oximes as antidotes of OP poisoning. The concept described herein relies on a combination of an amidine residue and oxime functionality whereby the amidine increases the binding affinity to the ChE and the oxime is responsible for reactivation. Amidine-oximes were tested in vitro and reactivation rates for OP-BuChE were greater than pralidoxime (2-PAM) or monoisonitrosoacetone (MINA). Amidine-oxime reactivation rates for OP-AChE were lower compared to 2-PAM but greater compared with MINA. After pretreatment for 30 min with oximes 15c and 15d (145 mu mol/kg, ip) mice were challenged with a soman model compound. In addition, 15d was tested in a post-treatment experiment (145 mu mol/kg, ip, administration 5 min after sarin model compound exposure). In both cases, amidine-oximes afforded 100% 24 h survival in an animal model of OP exposure.

• Polarity Umpolung Strategy for the Radical Alkylation of Alkenes

  Free radical-mediated alkylation of general alkenes is a challenging and largely unmet goal. Herein, we disclose a conceptually novel "polarity umpolung" strategy for radical alkylation of alkenes using a portfolio of easily-accessed, dual-function alkylating reagents. This is achieved by substituting inherently nucleophilic alkyl radicals with electrophilic sulfone-decorated surrogates, thus inverting

  自由基介导的一般烯烃的烷基化是一个具有挑战性且很大程度上未实现的目标。在这里，我们公开了一种概念上新颖的“极性化学极化”策略，该策略使用易于获得的双功能烷基化试剂进行烯烃的自由基烷基化。这可以通过用亲电砜修饰的替代物取代固有的亲核烷基自由基，从而改变通常的反应方式。随着烷基化，额外的杂芳基或肟基通过连续的对接和迁移过程同时并入烯烃，从而产生有价值的产品。该反应在温和条件下显示出宽泛的官能团耐受性。该协议为复杂的天然产物和含有烯烃部分的药物分子的后期修饰打开了新的前景。

  A photoredox decarboxylative coupling of N-hydroxyphthalimide esters with aldimines is reported for synthesizing α-amino esters. A broad scope of alkyl radicals generated under visible light irradiation adds to glyoxylate aldimines in reliably good to excellent yields. Adding inorganic bases such as potassium carbonate significantly enhanced the yields by suppressing the umpolung side reaction. The

  we describe a strategy for conversion of aliphatic C–H bonds to oxime ethers via hydrogen atom transfer. In this strategy, the decatungstate anion and sulfate radical play complementary roles in the abstraction of hydrogen atoms from primary, secondary, and tertiary C–H bonds of alkanes. The easy accessibility of alkanes and the broad substrate scope, mild conditions, and excellent regioselectivity

  coupling method has been developed for the single‐step generation of various γ‐amino acids and α,β‐diamino acids from α‐aminoacyl tellurides. Upon activation by Et3B and O2 at ambient temperature, α‐aminoacyl tellurides were readily converted into α‐amino carbon radicals through facile decarbonylation, which then reacted intermolecularly with acrylates or glyoxylic oxime ethers. This mild and powerful
