The key step is the generation of the new stereogenic centre in 4. From here, the reduction to 5 should be facile with e.g. samarium iodide.1 From 5 , the two steps to PZQ are known from the original report.2

5.10 Chirality at Nitrogen Phosphorus and Sulfur

Watch video · Introduction to chirality (handedness), and how chirality is related to the groups bonded to a central carbon. In the next video, we'll do a bunch of examples. We'll look at molecules, try to identify the chiral carbons, and then try to figure out whether the molecule itself is--Chiral examples 1 . Up Next. Chiral examples 1...

How To Identify The Sterogenic Centre In Chem Draw

First, try to identify all chiral stereogenic centers. Formulas having no chiral centers are necessarily achiral. Formulas having one chiral center are always chiral; and if two or more chiral centers are present in a given structure it is likely to be chiral, but in special cases, to be discussed later, may be achiral.

  • ChemDraw CDX files containing textboxes with Chinese characters were not imported. Chemical formula-like subscript of a Superatom S-group was read in reverse order from CDX when the group was to the left of the fragment.
  • First, try to identify all chiral stereogenic centers. Formulas having no chiral centers are necessarily achiral. Formulas having one chiral center are always chiral; and if two or more chiral centers are present in a given structure it is likely to be chiral, but in special cases, to be discussed later, may be achiral.
  • A carbon atom carrying four different groups is a stereogenic or chiral centre. For those who recognize a difference, the difference is that "stereocentre" or “stereogenic centre” is the more general term.
  • My molecule has 2 nucleophilic centres present, the phenol and a tertiary amine, and I want O-alkylation. I should also mention that in the previous step I isolate …
