Two new morphinandienone alkaloids, trans B/C-4-hydroxy-3,6-dimethoxy-5,6-didehydromorphinan-7-one (1, norocobotrine), and cis B/C-4-hydroxy-3,6-dimethoxy-5,6-didehydromorphinan-7-one (nildahilline), were isolated from Cuban endemic species Croton micradenus Urb. (Euphorbiaceae). Their structures have been elucidated by spectroscopic studies including 2D-NMR techniques

Abstract
Two new morphinandienone alkaloids, trans B/C-4-hydroxy-3,6-dimethoxy-5,6-didehydromorphinan-7-one (1, norocobotrine), and cis B/C-4-hydroxy-3,6-dimethoxy-5,6-didehydromorphinan-7-one (nildahilline), were isolated from Cuban endemic species Croton micradenus Urb. (Euphorbiaceae). Their structures have been elucidated by spectroscopic studies including 2D-NMR techniquesFile in questo prodotto:
