We demonstrated herein an I2O5-mediated radical nitration of olefins with NaNO2. A variety of (E)-nitroolefins can be synthesized in high yields and chemoselectivity.
我们在此证明了用NaNO 2进行的I 2 O 5介导的烯烃自由基硝化。可以高产率和化学选择性合成多种( E )-硝基烯烃。

alkene isomers. Here we report the remote oxidative halogenation of alkenes under palladiumcatalysis via which both terminal and internal alkenes yield primary alkyl halides efficiently. Engineering pyridine-oxazoline ligands by introducing a hydroxyl group is essential for achieving excellent chemo- and regioselectivity. The catalytic system is also good for the mixture of alkene isomers generated from

against Taq DNApolymerase. 6-(pent-4-enyloxy)-coumarin (7) IC50 = 48.33 ± 2.85 μM was defined as a small molecule able to disturb DNA replication. Docking and Molecular Dynamic Simulations suggest an active-site binding. Structure/activity relationship was reasonably established. Compound 7 represents a potential structure for further studies in the development of new anti-cancer DNA/polymerase binding
