Galbulimima belgraveana

Lew Mander of the Australian National University recently reported (J. Am. Chem. Soc. 2003. /25, 2400) the total synthesis of the pentacyclic alkaloid GB I3 3, which had been isolated from the bark of the rain forest tree Galbulimima belgraveana. In the course of the synthesis, he took full advantage of benzene precursors, while at the same time carefully establishing each of the eight stereogenic centers of... 

Only one species is attributed to the ancient relic family Himantrandaceae, but a large number of alkaloids have been isolated from it by a Sydney University group [44, 45]. The species, now known as Galbulimima belgraveana, occurrs in both New Guinea and north Queensland, and its content of alkaloids is very variable. They are, as might be expected, quite different in structure from any others, and some of the diverse types are represented by himbacine (25), himandridine (26) and himbadine (27). 

Galbulimima belgraveana (Himanthandraceae) is a large tree that reaches a height of 130 feet and is distributed in New Guinea, the Moluccas, and northern Australia (14). This plant contains over 25 alkaloids, mainly in the bark, albeit...
