Lincangenine
NettetA new benzylisoquinoline alkaloid, lincangenine-4- -D-glucopyranoside (1), has been isolated from the roots of Leontice altaica, together with 5 known alkaloids. Its structure was elucidated on the basis of 1D and 2D NMR data, and chemical means. Keywords: Leontice altaica, Alkaloids. Leontice altaica (syn. Gymnospermium altaicum, … NettetPseudotropine is prepared by classical nucleophilic displacement of the chloride with inversion of configuration (77%) ( Scheme 6 ). Hydrogenation of the double bond (98%), followed by conversion of the acetate to a mesylate (99%) sets the stage for cyclization (97%). Tropine is prepared by allylic amidation with retention of configuration (64%).
