Description
Fatemeh Hajian and co-authors report in 2026 a magnetic catalyst dressed with an amino acid for making ring compounds in a green way. The catalyst sits on polystyrene beads that a magnet can pull back after use. Its target is a three-part reaction that builds drug-like pyran rings.
Many checks confirm the coating took hold and the beads stay stable. Yields run from high eighties to near full across varied starting aldehydes at room heat. Runs finish in about twenty five minutes, far faster than many past routes. Six reuse rounds pass with no clear loss of power or form.
