, p. 943 - 946 (1993)
A pentacyclic aromatic alkaloid, kuanoniamine A (5) was synthesized from 6-methoxybenzothiazole-4,7-dione (7) and 2-aminoacetophenone (8).Similarly, 11-hydroxyascididemin (4) was prepared from 6-bromo-4-chloro-5,8-dimethoxyquinoline (12).The structure of neocalliactine acetate, a derivative of calliactine, was determined as 19 by total synthesis from 6-methoxy-5,8-quinolinedione (23) and 2-amino-5-methoxyacetophenone (24).

Marine compounds with pyridoacridine skeletons are known to exhibit interesting antitumor activities. Ascididemin has already been reported as displaying significant antitumor activities in vitro and has also been found to have a relatively high global to

A pentacyclic aromatic alkaloid, kuanoniamine A (6) was synthesized in three steps from 6-methoxybenzothiazole-4,7-dione (8) and 2-aminoacetophenone (9). 11-Hydroxyascididemin (4) was prepared from 5,8-quinolinedione (13, 14) or 1,4-acridinedione (20). The structure of neocalliactine acetate, a derivative of calliactine, was determined to be 5 by total synthesis from 6-methoxy-5,8-quinolinedione (28) and 2-amino-5-methoxyacetophenone (29).
Polycyclic Aromatic Alkaloids, 8. The Structure of Neocalliactine Acetate - Proof by Total Synthesis
Bracher, Franz
, p. 1205 - 1208 (2007/10/02)
The pentacyclic compound 1 is prepared in six steps by starting from 5,8-quinolinedione (7).Its spectral data are in accordance with those of neocalliactine acetate, a derivative of the marine alkaloid calliactine.This represents the first definite confir
