  • NHC-Cu(I)-Catalyzed Friedländer-Type Annulation of Fluorinated <i>o</i>-Aminophenones with Alkynes on Water: Competitive Base-Catalyzed Dibenzo[<i>b</i>,<i>f</i>][1,5]diazocine Formation

    good yields. Further investigations proved that o-FMKs could be efficiently transformed into a rare class of heterocyclic compounds—dibenzo[b,f][1,5]diazocines—by a base-catalyzed condensation, also on water. The developed method was applied for gram-scale synthesis of a fluorinated analogue of G protein-coupled receptor antagonist (GPR91).

  • Successive Copper(I)-Catalyzed Cross-Couplings in One Pot: A Novel and Efficient Starting Point for Synthesis of Carbapenems
    作者:Biao Jiang、Hua Tian、Zuo-Gang Huang、Min Xu
    DOI:10.1021/ol800845r
    日期:2008.7.3
    An efficient approach for synthesizing a series of 2-sulfide carbapenems has been developed using two successive Cu(I)-catalyzed cross-couplings in a single pot. The method involves highly selective intramolecular coupling of lactam and dihaloalkene using 2,2'-bipyridine as a ligand, followed by intermolecular C-S formation in the presence of another ligand (1,10-phenanthroline, PPh 3) and mercaptan
    使用单个罐中两个连续的Cu(I)催化的交叉偶合,已经开发了一种合成一系列2-化碳青霉烯的有效方法。该方法包括使用2,2'-联吡啶作为配体进行内酰胺和二卤代烯烃的高选择性分子内偶联,然后在另一种配体(1,10-咯啉,PPh 3)和醇的存在下进行分子间CS形成。

    In the present work, the validity of the helicity rule relating the absolute configuration of the bridgehead carbon atom in bicyclic β-lactams to the sign of the 220 nm band observed in their electronic circular dichroism (ECD) spectra is examined for ring-expanded cephalosporin analogues. To this end, a series of model compounds with a seven-membered ring condensed with the β-lactam unit was synthesized
    在目前的工作中,对于环扩展的头孢菌素,研究了将双环β-内酰胺中桥头碳原子的绝对构型与在其电子圆二色性(ECD)光谱中观察到的220 nm谱带的符号相关的螺旋规则的有效性。类似物。为此,合成了具有与β-内酰胺单元稠合的七元环的一系列模型化合物。它们合成的关键步骤是闭环复分解(RCM)或自由基环化,导致双环骨架中6位上具有S,O或C原子的七元环。为了研究简单,凭经验建立的螺旋度规则的范围和局限性,该规则结合了ECD光谱,变温ECD测量,X射线分析,并使用了随时间变化的密度泛函理论(TD-DFT)计算。将实验性ECD光谱与TD-DFT计算模拟的光谱进行比较,可以合理解释在240-215 nm光谱范围内观察到的Cotton效应。结果表明,螺旋度规则不适用于所研究的化合物,因为它们的酰胺发色团具有平面性。因此,这些化合物不构成仅对具有非平面酰胺生色团的双环和多环β-内酰胺建立的规则的例外。结果表明,

    The borylstannane [-N(Me)CH2CH2(Me)N-]B-SnMe3 is a superior reagent capable of effecting bisfunctionalization-cyclization in several highly functionalized 1,n-diynes, 1,n-enynes, and 1,n-allenynes (including 1,2-dipropargylbenzenes, 2,2'-dipropargylbiphenyls, 4,5-dipropargyldioxolanes, and 1,4-dipropargyl-beta -lactams) where the more well-known silylstannanes fail. Variable-temperature NMR studies showed that conformational restraints imposed by selected backbones increase the activation barrier for the helical isomerization in (Z,2)-dienes that are generated in the cyclization of the diynes. In the biphenyl and dioxolane systems, the reactions proceed with surprisingly good regio- and stereoselectivity. The resulting diazaborolidine derivatives are hydrolytically unstable but can be isolated by recrystallization or precipitation. For further synthetic applications, it is advantageous to convert these compounds in situ into the corresponding dioxaborolidines with either retention of the Me3Sn group or replacement of this group via halodestannylation. The configurations of the vinyl moieties are preserved in these reactions. Highly functionalized dibenzocyclooctadienes, which adorn the carbon frames of several important cytotoxic natural products, can be synthesized using this chemistry.
