Synthesis of benzo[b]carbazoloquinones by coupling of organostannanes with bromoquinones

The synthesis of 5-carbonitrile-1,7-dihydroxy-3-methyl-SH- benzo[b]carbazole-6,11-dione, the quinone originally proposed as prekinamycin, was completed by using a palladium and copper catalyzed Stille reaction as the key step. A subsequent heterocyclizati

Regioselective Synthesis of the Kinamycin ABCD ring system

The new bromoquinone-enamine annulation was successfully extended to acyclic enamino ketones resulting in a new synthesis of the ABC framework 7 of kinamycins and when applied to cyclic enamino ketones 8a-c the first synthesis of their ABCD ring system.Smooth aromatisation of compounds 4b,d to 9a,b respectively was effected with DDQ. - Key Words: regiospecific annulation, metal catalysed; kinamycin; tetrahydrobenzocarbazole
