The structure for laetine (2-hydroxy-1-methyl 10,11-methylenedioxy noraporphine), a new alkaloid from the bark of Litsaea laeta has been established.N,O-Dimethylharnovine and glaucine were also isolated from the same source.C-2 hydroxy aporphines are characteristic of L. laeta.Two known alkaloids, dicentrinone and nordicentrine, have also been isolated from the leaves of L. salicifolia. - Key Word Index: Litsaea laeta; L. salicifolia; Lauraceae; new noraporphine alkaloid; structure determination.

Novel total syntheses of oxoaporphine alkaloids such as liriodenine, dicentrinone, cassameridine, lysicamine, oxoglaucine and O-methylmoschatoline were developed. The key step of these total syntheses is Cu-catalyzed conversion of 1-benzyl-3,4-dihydro-isoquinolines (1-Bn-DHIQs) to 1-benzoyl-isoquinolines (1-Bz-IQs) via tandem oxidation/aromatization. This novel Cu-catalyzed conversion has been studied in detail, and was successfully used for constructing the 1-Bz-IQ core.
