This method allowed carbon-carbon bond formation of “non-activated” aziridine via aziridinium ion ring-opening in regio- and stereo-selective manner for the first time. This newly developed reaction was applied for an efficient synthesis of alkaloid with the representative example of conine and epiquinamide.</p> 2019-06-27 08:58:41 aziridine bicyclic aziridinium ions alkylation ring-expansion alkaloid synthesis
