Toll-likereceptor (TLR) 7 and 8agonists can potentially be used in the treatment of viral infections and are particularly promising for chronic hepatitis B virus (HBV) infection. An internal screening effort identified a pyrimidine Toll-likereceptor 7 and 8 dual agonist. This provided a novel alternative over the previously reported adenine and pteridone type of agonists.

The synthesis of a macrocyclic Ru carbene catalyst for selective cross alkenemetathesis is reported. The new catalyst showed different reactivity for various type 1 alkenes in homodimerization which correlated with the aggregrate size of the allylic substituent. The altered reactivity profile allowed for selective product formation in competition cross alkenemetathesis between two different type
A Simple One-pot Organometallic Formylation/Trapping Sequence Using<i>N</i>-Formylcarbazole

日期:——
Treatment of a range of sp3-, sp2- and sp-nucleophiles with N-formyl carbazole leads to the formation of the metastable anionic carbazole carbinols. In the presence of a second nucleophilic reagent such as phosphonoacetate or an organolithium, these collapse on warming to the aldehyde which is trapped in situ to afford the α,β-unsaturated esters or secondary carbinols respectively.
