Palladium-Catalyzed Direct C2-and Further C7-Acylation of Indoles with Aldehydes

The palladium‐catalyzed direct C2‐ and further C7‐acylation of indoles with aldehydes have been developed. This method provides a convenient pathway toward a variety of mono‐ and diacylated indoles.     

Lipase‐Supported Metal–Organic Framework Bioreactor Catalyzes Warfarin Synthesis

A green and sustainable strategy synthesizes clinical medicine warfarin anticoagulant by using lipase‐supported metal–organic framework (MOF) bioreactors (see scheme). These findings may be beneficial for future studies in the industrial production of chemical, pharmaceutical, and agrochemical precursors.     

Luminescent Ag6Au6 Heterometallic Ethisterone Cluster and Probe for Estrogen Receptor α

A heterometallic cluster [Ag₆Au₆(ethisterone)₁₂] of an unprecedented topology was synthesized and characterized. A sensitive and specific probe for estrogen receptor α (ERα) has been developed for the first time based on the enhancement of the Ag₆Au₆ luminescence.     

从事件历史研究上海私车额度拍卖政策绩效

借鉴力学史研究思路和力学基本原理, 从上海私车额度拍卖政策相关历史事件变迁的角度, 研究政府对私车拥有权进行干预的情形下, 私人机动车与社会经济发展的关系, 以此评估政策绩效. 分析表明, 从2002 年至2013 年, 推动个人民用车辆增长主要因素为人口增长、道路建设和公交设施投入(万人公交车拥有量), 阻碍因素包括系统惯性、额度投放量以及与政策事件相关联的"作用力"; 与预期目标相比, 额度拍卖政策的作用效果显得相当微弱.     

Synthesis of Dibenzo[c,e]oxepin‐5(7H)‐ones from Benzyl Thioethers and Carboxylic Acids: Rhodium‐Catalyzed Double C?H Activation Controlled by Different Directing Groups

A rhodium(III)‐catalyzed cross‐coupling of benzyl thioethers and aryl carboxylic acids through the two directing groups is reported. Useful structures with diverse substituents were efficiently synthesized in one step with the cleavage of four bonds (C H, C S, O H) and the formation of two bonds (C C, C O). The formed structure is the privileged core in natural products and bioactive molecules. This work highlights the power of using two different directing groups to enhance the selectivity of a double C H activation, the first of such examples in cross‐oxidative coupling.
