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). WebAug 16, 2024 · Whereas for the other three chiral columns, the MJ(2)-RH and ND(2)-RH columns afforded almost no chiral recognition toward penthiopyrad enantiomers. The MD(2)-RH column only partially separated penthiopyrad enantiomers in both tested ACN/water and MEOH/water mobile phases. Given its substantially better performance, …

Photonic bound states in the continuum (BICs) describe exotic localized eigenstates embedded in the continuum spectrum. Since its initial mathematical prediction in quantum mechanics, [] the concept of BICs has been explored in both quantum and classical regimes.
