Question
Chapter 4, Problem 37P
Interpretation Introduction
Interpretation:
Stereochemistry of the drug droxidopa is to be shown using appropriate wedges and dashes in such a way that the configurations
Concept introduction:
On the basis of Cahn-Ingold-Prelog (CIP) rules, the absolute configuration at a chiral center is determined.
After orienting the molecule such that the lowest priority group is away from the observer, if atom/group priorities excluding the lowest priority group follow a clockwise path, the absolute configuration is R. If the path followed is counterclockwise, the absolute configuration is S.
