Introduction of adjacent oxygen-functionalities in dimethyl heptalenedicarboxylates

The bromination of dimethyl 8-methoxy-1,6,10-trimethylheptalene-4,5- dicarboxylate (6; Scheme 2) with N-bromosuccinimide (NBS) in N,N-dimethylformamide (DMF) leads in acceptable yields to the corresponding 9-bromoheptalenedicarboxylate 10 (Table 1). Ether
