Overcoming the ring tension: computational approaches to stereochemical assignments and geometrical insights in small heterocycles

In this study, we evaluate the performance of the DP4+ and MM-DP4+ methods on molecules featuring small heterocyclic rings. A dataset of 71 molecules containing three- and four-membered heterocycles, known for their stereochemical assignment challenges, was analyzed. We compared molecular geometries...
