Abstract:
|
The structures of three alkaloids isolated from Guatteria dielsiana, 6-methoxyonychine, dielsine and
dielsinol, originally described as l-azafluoren-9-ones, are revised to 4-azafluoren-9-ones on the basis of previous
synthetic work and current studies on alkaloids of the Annonaceae. Synthetic 6-methoxyonychine (6-methoxy-lmethyl-
4-azafluoren-9-one) is shown to be identical with the natural product. |
