WebApr 10, 2024 · Chiral resolution of simple spin crossover chelates complexes into the Δ and Λ forms offers a facile route to homochiral magnetic switches, which could be easily enantiomerically enriched. Here, we report the spontaneous resolution of new hysteretic spin crossover complex, [MnIII(sal2323)]SCN·EtOH (1), into Δ and Λ forms, without the use ... WebEnantiomers are stereoisomers that are non-superimposable mirror images. Enantiomers differ at the configuration of every stereocenter. They can be understood in terms of handedness, like gloves for the right or left hands. Molecules that are not mirror images but differ in spatial arrangements of atoms are diastereomers.

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). WebSep 4, 2024 · In chemistry, chirality usually refers to molecules. Two mirror images of a chiral molecule are called enantiomers or optical isomers. Why is chirality important in chemistry?
