Total synthesis of ascididemin-type alkaloids using alkyne building blocks

A common approach to ascididemin-type alkaloids, including ascididemin, bromoleptoclinidinone, neocalliactine acetate, and 11-hydroxyascididemin, based on a Bronsted acid-promoted tandem annulation has been developed. Alkyne building blocks were first des

Synthetic studies on pentacyclic aromatic alkaloids, kuanoniamine A, 11-hydroxyascididemin, and neocalliactine acetate

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

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
