Cryptocarya bowiei

Cryptaustoline (1) and (-)-cryptowoline (2) were obtained as iodides from the Australian plant Cryptocarya bowiei (Hook) Druce, and their structures... 

Early attempts to simulate the synthesis of the aporphine and morphine alkaloids often met with failure. Efforts to oxidize laudanosoline (30), for example, did not give the desired type of coupling, but resulted in the formation of dibenzopyrrocoline structures (Fig. 32.30) (Elliott, 1987 Geissman and Crout, 1969). Alkaloids of this general structure were discovered in the Australian plant Cryptocarya bowiei (Lauraceae). Among these were cryptaustoline (91) and cryptowolline (92).
