Various organocatalysts have been developed for the aldol reaction but particular attention has been paid to prolinamide derivatives. They are easy to prepare and their catalytic activity can be readily tuned through structural modification. In this

Vitamin B12 is an attractive candidate for a drug or an imaging-agent carrier into cells, due to its dietary uptake and well established transport through glycoproteins. Utilization of this system requires an appropriate functionalization of vitamin

RNAs directly regulate a vast array of cellular processes, emphasizing the need for robust approaches to fluorescently label and track RNAs in living cells. Here, we develop an RNA imaging platform using the cobalamin riboswitch as an RNA tag and a s

Unwanted copper insertion into a free base porphyrin starting material during Cu -catalyzed [1,3] azide-alkyne dipolar cycloaddition ( CuAAC ) is not observed when using (1,10-phenanthroline)-bis(triphenylphosphine)copper(I) nitrate as a catalyst. Re
