Disulfide modification and thiol protection via tris(trimethylsilyl)silane-mediated hydrosilylation of disulfides
Abstract Thiol functionalities are indispensable in both biological and synthetic chemistry. However, unlike the powerful silylation strategies for hydroxyl groups, widespread applications in sulfur chemistry are severely hampered by the weak and hydrolytically labile nature of the Si–S bond. Here, we report that tris(trimethylsilyl)silane (TTMSS), a unique trisilyl-substituted reagent, efficiently enables the rapid hydrosilylation of disulfides under exceptionally mild conditions.
Carbene-organocatalyzed enantioselective [5+5] annulation of dienols and dienals towards tetrahydroisochromen-1-ones
Carbene-organocatalyzed enantioselective [5+5] annulation of dienols and dienals towards tetrahydroisochromen-1-ones An N-heterocyclic carbene (NHC)-catalyzed [5+5] annulation between dienals and dienols was developed for the synthesis of multisubstituted tetrahydroisochromen-1-ones. The absolute configuration of three diastereoisomers of product were carefully checked with single-crystal X-ray diffraction.

The Effects of Social Media Communication and e-WOM on Brand Equity: The Moderating Roles of Product Involvement
Abstract : As brand equity (BE) is a valuable, but intangible, asset of any firm, understanding BE represents a primary task for many organizations. Factors that influence the development of BE are of inordinate academic and practical significance and a source of continuous investigation.
Carbene-Catalyzed [3+2+1] Annulation via C-N Radical Coupling of Iminyl Radicals and Ketyl Radicals
Carbene-Catalyzed [3+2+1] Annulation via C-N Radical Coupling of Iminyl Radicals and Ketyl Radicals Wenchang Li, Peng Zhou, Qing Zhao, Kejun Lin and Tingshun Zhu Abstract An N-heterocyclic carbene-catalyzed cascade [3+2+1] annulation to assemble vinyl azides, aldehydes and trihalomethyl reagents (Togni’s reagent or CCl4) towards 1,3-oxazin-6-ones was reported.
Stereoselective Migratory Heteroaryltrifluoromethylation of Allylic Amine via Electrosynthesis
Stereoselective Migratory Heteroaryltrifluoromethylation of Allylic Amine via Electrosynthesis Jianyong Lan, Kejun Lin, Xing Zhang and Tingshun Zhu Abstract An electrochemical initiated heteroaryltrifluoromethylation of allylic amine was developed. The cascade reaction involved anodic oxidation of Langlois reagent (CF3SO2Na) to generated CF3 radical, radical addition to the unactivated alkene, Smiles-type heteroaryl migration and reduction of nitrogen radical.
