Chapter 5, Problem 5.70P

Interpretation Introduction

Interpretation: The stereogenic centers in the given compound are to be located. Each stereogenic center is to be labeled as $R$ or $S$.

Concept introduction: An atom bearing four different atoms or groups which produces stereoisomers on interchange of any two groups are stereogenic centers.

The stereogenic centers with $R,S$ configuration are assigned according to Cahn-Ingold-Prelog rules. According to these rules, the substituents attached to stereogenic centers are given priority. On moving from higher priority to lower priority substituent in clockwise direction, the compound is assigned with $R$ configuration. On moving from higher priority to lower priority substituent in anticlockwise direction, the compound is assigned with $S$ configuration.
