Witryna26 paź 2024 · This leads into an important concept of prochirality. A prochiral molecule refers to one that has no chiral centre prior to the reaction but will have a chiral centre after the reaction [3]. An example of this is shown in Figure 1. In the original compound on the left, the molecule is achiral as there is no chiral centre.
