Web2 days ago · Chirality is defined as an important property of asymmetry in several branches of science. The term chirality has derived from a common chiral entity, which is the Greek “side”. If it is distinguishable from its mirror image, a system or entity is chiral; that is to say, it cannot be superimposed over it. Chirality is an asymmetric quality that is relevant in many fields of science. The word chirality comes from the Greek (kheir), which means “hand,” a common chiral item. A chiral item or system is distinct from its mirror image; that is, it cannot be overlaid onto it.

WebAug 29, 2014 · Stereocenters are labeled R or S. The "right hand" and "left hand" nomenclature is used to name the enantiomers of a chiral compound. The stereocenters are labeled as R or S. Consider the first picture: a curved arrow is drawn from the highest priority ( 1) substituent to the lowest priority (4) substituent. Webvaluable potential of axially chiral BINOL-derived phosphoric acids as robust hydrogen-bonding catalysts in asymmetric Mannich reactions [13, 14]. Their discovery spawned intense research into organocatalysis and chiral Brønsted acid catalysis, from where the application of axially chiral skeletons in asymmetric catalysis vastly expanded.
