WebChiral chromatography. This term has become very popular and commonly used in practice. But the appropriate expression is "enantioselective chromatography". Chiral … 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).
