Why stereochemistry is not just about seeing molecules—but learning how to describe them In modern chemistry, we have powerful tools like X-ray crystallography that can reveal the exact three-dimensional structure of a molecule with remarkable precision. So it raises a compelling question: If we already know what a molecule truly looks like in 3D… why …
A Quiet Revolution in Asymmetric Synthesis tert-Butanesulfinamide, widely known as Ellman’s sulfinamide, is one of the most influential chiral auxiliaries in modern asymmetric synthesis. Developed in the 1990s by the laboratory of Jonathan Ellman, this sulfur-centered chiral reagent revolutionized the stereoselective construction of amines—key structural motifs in pharmaceuticals and agrochemicals. Its configurationally stable stereogenic sulfur …
A chiral perspective on how we describe, teach, and encode molecular handedness in the age of artificial intelligence Prelude Chiral molecules are not flat drawings on paper (2D). They live in space (3D). They twist, reflect, and occupy three dimensions in ways that decide how they bind to receptors, how they are metabolized, and ultimately …
Can an AI truly understand a molecule if it cannot tell left from right? Artificial intelligence now shapes the earliest and most consequential stages of drug discovery, from virtual screening and ADMET prediction to generative molecular design. Yet many of these systems operate in an effectively achiral digital environment, where molecules are represented as flat …

Where a molecule’s handedness meets clever engineering—shaping safer, more precise, and more effective medicines. Introduction: Why Chirality Matters in Drug Engineering In the world of drug design, a subtle twist in molecular geometry can change everything. Two molecules may share the same atoms and bonding pattern yet behave like entirely different substances simply because they …
