WebOct 5, 2024 · S -> R), so doing one swap, followed by a second swap gets back to the original configuration (eg. S -> R -> S). So, rather than rotating like I did in (2), you could draw out the chiral centre with 1, 2, 3, 4, then do two sequential swaps that end up putting the lowest priority group going away from you (ie. with the hashed bond).
