Chirality center meaning
WebStereochemistry is an important issue in any synthesis. This chapter illustrates two key points. First, disconnection should be done at a C C bond where one of the carbon atoms is a stereogenic center. Disconnection of a bond away from the stereogenic center usually leads to a less efficient and less desirable retrosynthesis, and often more ... WebIn humans, chirality (also referred to as handedness or laterality) is an attribute of humans defined by their unequal distribution of fine motor skill between the left and right hands. …

These centers can be described as R or S, meaning the molecule can have either “right-handedness” or “left-handedness”. Label the groups by priority 1-4, with the highest priority being 1. If two atoms are the same, look to the next connected atom.
