Chiral biology
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. WebHerein, we disclose a new catalytic asymmetric tandem reaction based on the Heyns rearrangement for the synthesis of chiral α-amino ketones with readily available …
