the enol intermediate in the reaction catalyzed by typeIIdehydroquinase were synthesized to investigate the effect on the inhibition potency of replacing the oxygen atom in the side chain by a carbon atom. The length and the rigidity of the spacer was also studied. The inhibitory properties of the reported compounds against typeIIdehydroquinase from Mycobacterium tuberculosis and Helicobacter pylori

Diverse alkenylboronic acids react smoothly with various sp3‐carbon electrophiles such as unactivated alkyl triflates in the presence of mild bases such as K3PO4. The reaction protocol is very mild and thereby enables high functional group tolerance. This transition metal‐free condition is orthogonal towards the classic transition metal catalyzed Suzuki coupling.
在温和的碱(例如K 3 PO 4)存在下,不同的烯基硼酸与各种sp 3-碳亲电试剂(例如未活化的烷基三氟甲磺酸酯)平滑反应。反应方案非常温和,因此可以实现较高的官能团耐受性。这种无过渡金属的条件与经典的过渡金属催化的Suzuki偶联正交。

Replacement of deoxyguanosine (dG) nucleobases within G-tetrads of G-quadruplex folding oligonucleotides with donor (D)/acceptor (A) fluorescent 8aryldG residues provides diagnostic FRET signalling for G-quadruplex detection.
