## Abstract The 2 + 4 cycloaddition reaction of 1,4โnaphthoquinone and substituted styrenes was used to prepare 1โ, 2โ, 3โ, and 4โbromobenz[a]anthraceneโ7,12โdiones (BADs). The corresponding bromobenz[a]anthracenes (BAs) were prepared by aluminum tricyclohexoxide reduction of the diones. Lithiation
The syntheses of 7,12-Dioxa-benzo[a]anthracenes bearing in C6 a earboxymethyl group and 5aza analogues are described. The key steps are intramoleeular cyclisations of 3-arylbenzo [ 1,4]dioxin-2diethylcarboxamides and palladium catalysed methoxyearbonylation of aryl triflates.
