The present invention relates to compounds and methods for the treatment of bacterial infections. Because their mechanism of action does not involve killing of bacteria or inhibiting their growth, the potential for these compounds to induce drug resistance in bacteria is minimized. Through inhibiting bacterial virulence, the present invention provides a novel means of treating bacterial infections.

The application of a dual reactor coil for consecutive photochemical reactions is presented in continuous flow mode. This strategy enables for the first time the use of a single LED-based lightsource to perform two distinct photochemical reactions in an uninterrupted fashion. This approach is demonstrated for the telescoped synthesis and functionalisation of drug-like quinolines and compared to alternatives
双反应器线圈在连续光化学反应中的应用以连续流动模式呈现。该策略首次实现了使用单个基于 LED 的光源以不间断的方式执行两个不同的光化学反应。这种方法被证明用于类药物喹啉的伸缩合成和功能化,并与利用两个顺序运行的光化学反应器设置的替代方法进行了比较。所提出的策略能够在现代合成中加强光化学反应的开发。

The first total synthesis of cancer chemopreventive terpenyl hydroxychalcone xanthoangelol J isolated from Angelica keiskei was accomplished with asymmetric epoxidation, aromatic C-alkylation and Claisen-Schmidt condensation via enol mode as key steps. The crucial Claisen-Schmidt condensation has been accomplished by a novel green method using KHSO4-SiO2 as a recyclable catalyst under microwave activation. The absolute configuration of the molecule was also determined. (C) 2013 Elsevier Ltd. All rights reserved.
A simple and highly efficient method for the synthesis of chalcones by using borontrifluoride-etherate

Chalcones are secondary metabolites of terrestrial plants, precursors for the biosynthesis of ilavonoids and exhibit various biological activities. Condensation of substituted acetophenones (2a-12a) with various aromatic aldehydes (1b-7b) in the presence of BF3-Et2O at room temperature gave chalcones in 75-96% yield.
