RS-Stereoisomeric Groups and Enumeration of Quadruplets of RS-Stereoisomers

Abstract

The RS-stereoisomeric group T d σ ˜ I ˆ for characterizing stereoisograms based on a tetrahedral skeleton is formulated by starting from the point group T d Each stereoisogram consists of a quadruplet of promolecules, which is governed by the RS-stereoisomeric group. The number of quadruplets with a given set of proligands is calculated by the extended unit-subduced-cycle-index (USCI) approach. The representative promoleucles of the resulting quadruplets are depicted in a tabular form.
