  • Extended Aromatic and Heteroaromatic Ring Systems in the Chalcone–Flavanone Molecular Switch Scaffold
    作者:Brian M. Muller、Theodore J. Litberg、Reid A. Yocum、Chanté A. Pniewski、Marc J. Adler

    日期:2016.7.1
    substitutions alter the pH range in which rapid interconversion occurs. Herein, more impactful structural modifications were performed via alteration of the characteristic phenyl rings to alternative aromatic systems. It was determined that the scaffold was still viable after these changes and that the range of accessible midpoint pH values was markedly increased. To further explore the switch’s scope, scaffolds
    以前对邻羟基查耳酮/黄酮酮分子转换支架的研究表明,简单的取代改变了发生快速相互转化的pH范围。本文中,通过将特征性苯环改变为替代的芳族体系进行了更具影响力的结构修饰。确定在这些改变之后,支架仍然是可行的,并且可达到的中点pH值的范围显着增加。为了进一步探索开关的范围,还研究了能够发生多个开关事件的支架。
  • Iodine catalyzed one-pot synthesis of flavanone and tetrahydropyrimidine derivatives via Mannich type reaction

    A variety of functionalized flavanone derivatives and tetrahydropyrimidine derivatives were achieved under remarkably mild conditions. The combination of good to excellent yields, a simple work-up, and the high compatibility of functional groups makes this an attractive synthetic approach to access flavanone and tetrahydropyrimidine derivatives.

    flavanones, which included polycyclic aromatic and heterocyclic rings, were readily synthesized via oxa-Michael addition from the corresponding hydroxychalcones with a catalytic amount of aqueous cesium fluoride solution under mild conditions. This method could be applied to the scalable synthesis of eriodictyol as a known potent inhibitor of the SARS-CoV-2 spike protein.

    日期:2015.3
    Chromone has been noted to be one of the most challenging substrates in the asymmetric 1,4‐addition of α,β‐unsaturated carbonyl compounds. By employing the rhodium complex associated with a chiral diene ligand, (R,R)‐Ph‐bod*, the 1,4‐addition of a variety of arylboronic acids was realized to give high yields of the corresponding flavanones with excellent enantioselectivities (≥97 % ee, 99 % ee for
    在不对称的α,β-不饱和羰基化合物的1,4加成反应中,苯醌是最具挑战性的底物之一。通过使用与手性二烯配体(R,R)-Ph-bod *缔合的铑配合物,实现了各种芳基硼酸的1,4加成,从而获得了高产率的相应黄烷酮,具有出色的对映选择性(≥ ee为97%ee,大多数基材为99%ee)。在规定的反应条件下,未观察到会导致产物对映选择性下降的开环副产物。
