Abstract

(IV)(V)(VI)(VIII the product was anthracene, produced by cyclisation of the keto-ester (V) to the perhydroanthracene derivative (VII), which by the subsequent procedure yielded anthracene. This unexpected result confirms our view that the ester group is attached at C (lzl in the original adduct. The intermediate (V) could arise if the ester group was attached at position 3, but the previous evidence is against this. An adduct containing the ester group ...
