Abstract:
Two diastereoisomeric N-doped nanographene derivatives have been efficiently prepared in two synthetic steps starting from an ethynylated hexaazatriphenylene building block. The first derivative adopts a D3 -symmetrical propeller-shaped structure with three equivalent nanographene foils. The structure of the second diastereoisomer is C2 -symmetrical and differs from the first one by the way two peripheral nanographene foils overlap. Owing to their intertwined structures, the two N-doped nanographenes are soluble in organic solvents and could be characterized by a combination of several analytical tools. Resolution of the D3 -symmetrical derivative has been achieved and CD measurements revealed extremely strong Cotton effects.

Dehydration Synthesis
Dehydration synthesis (also called a condensation reaction) is the chemical process in which two molecules covalently link together to form a new molecule, along with the release of a water molecule. Many physiologically important compounds form by dehydration synthesis reactions, such as complex carbohydrates, proteins, DNA, and RNA.

Lagging Strand Synthesis
There are several major differences between synthesis of the leading strand and synthesis of the lagging strand. 1) Leading strand synthesis happens in the direction of replication fork opening, whereas lagging strand synthesis happens in the...
Transfer RNA Synthesis
Each of these chemical modifications is carried by a specific enzyme, post-transcription. All of these enzymes have unique base and site-specificity. Methylation, the most common chemical modification, is carried by at least nine different enzymes, with...
