Preparation of the 5-substituted azepino [3,4-b]indole core structure can be realised through a catalytic Heck reaction. The scope and limitations of this methodology are reported. The reactivity of di-tert-butyl 5ethoxycarbonylmethylene-1,3,4,5-tetrahydro-1-oxoazepino[3,4-b]indole-2,10-dicarboxylat
Monoor dibromo derivatives 2 and 3 were prepared by an efficient two-step route from 10-methyl-azepino [3,4-b]indole-1,5dione 1. Elimination reaction on 2 gave access to 4-bromo-10-methyl-2H,10H-azepino[3,4-b]indole-1,5-diones 4. Finally, 4-substituted 10methyl-2H,10H-azepino [3,4-b]indole-1,5-dione
