The feature that is most often the cause of chirality in molecules is the presence of an … WebChirality (chemistry) The term chiral (pronounced /ˈkaɪɹ (ə)l̩/) is used to describe an object that is non-superimposable on its mirror image. Human hands are perhaps the most universally recognized example of chirality: the left hand is a non-superimposable mirror image of the right hand: no matter how the two hands are oriented, it is ...
WebApr 12, 2024 · We have developed a chiral phosphoric acid-catalyzed enantioselective Friedel–Crafts alkylation reaction between pyrroles and indolylmethanols. Wide substrate scope was observed, and a chiral all-carbon quaternary center was constructed at the 3 position of indoles in high yields with high to excellent enantioselectivities (up to 99% ee). WebWhy life is chiral has puzzled scientists for well over a century. Louis Pasteur famously discovered molecular chirality in his meticulous experiments in 1848. He separated by hand the mirror-image forms of salts of tartaric acid and saw that their solutions will rotate the plane of polarised light in opposite directions.
