Abstract:
A formal enantioselective total synthesis of bisdehydroneostemoninine employing L-glutamic acid as the chiral pool is described. The key features of the synthesis include regioselective and enantioselective opening the chiral epoxide with dimethylsulfonium methylide and tandem Friedel-Crafts cyclization followed by lactonization to form the 5-7-5 tricyclic core of the target stemona alkaloids. The synthetic route provides opportunities to explore the biological behavior of enantiopure bisdehydroneostemoninine. [Formula: see text].

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...
