A general synthetic route to enantiopure quinoline alkaloids
Barr,Boyd
, p. 153 - 154 (1994)
Enantiopure chromenoquinoline epoxides of established configuration are obtained by cyclization of their resolved bromomethoxy(trifluoromethyl)phenylacetates and provide a new route to geibalansine, O-acetylgeibalansine, ribalinine, araliopsine, edulinine and related quinoline alkaloids.
