An aerobic oxidative cross-dehydrogenative coupling reaction between sp3 C–H and sp2 bonds is developed by employing a vanadium catalyst (10 mol%) in an aqueous medium using molecular oxygen as the oxidant. This environmentally benign strategy exhibits larger substrate scope shows high regioselectivity.

In this study we developed a very simple and rapid miRNA 21 detection system using novel quinolinium diethylamino salicylaldehyde (QnDESA) probe for sensing the 22AG hybrid G-quadruplex with single-step rolling circle amplification (RCA) reaction. We synthesized circular DNA padlock template containing sequence complementary to G-quadruplex, used SplintR ligase ensure perfect hybridization 21, applied phi-29 polymerase tandem of sequence, then probed product QnDESA. This combination...

In this paper, we report a stepwise RNA-primed RNA polymerization method for the site-specific incorporation of multiple fluorescent moieties into RNA, mediated by an polymerase. A screen several polymerases revealed that T7 polymerase was only one functioned in polymerization. first fluorescence labeling step, rUthioTP residue incorporated directly using polymerase; second step performed post-labeling strategy: introducing rUamiTP polymerase, and then reacting with ylidenemalononitrile...
