Add time:07/15/2019 Source:sciencedirect.com
Brønsted and Lewis acid-catalysed reactions of the 23-methoxycarbonyl furospirostanic side chain are described. While bromination, deuteration and BF3·Et2O/AcOH treatment involve regioselective F-ring opening with exclusive participation of Δ22-furostenic intermediates, BF3·Et2O/Ac2O treatment leads to irreversible E- or F-ring cleavage.
