Abstract
Directed metallation of the diethoxymethyl protected indole 4 followed by t reatment with beta-nitrostyrene leads to the 1,2-disubstituted indole 5. Us ing 5 as a central intermediate, the tricyclic annellation products of type 2 and 3 were accessed when the regiochemical outcome of the reactions coul d be controlled.
