WebMar 16, 2024 · Chiral proline is termed as the simplest bifunctional organocatalysts (Scheme 10.1. 1 ). This amino acid is called as “simplest enzyme” due to its ability to catalyze reactions with high stereoselectivity. Scheme 10.1. 1: Forms of Proline Available. L-Proline is a small molecule, non-toxic, inexpensive, readily available in both ... WebPreferential selection of a given enantiomer over its chiral counterpart has become increasingly relevant in the advent of the next era of medical drug design. In parallel, cavity quantum electrodynamics has grown into a solid framework to control energy transfer and chemical reactivity, the latter requiring strong coupling. In this work, we derive an …
