- Synthesis of substituted azepino[3,4-b]indole-1,5-diones

Cyclic β-amino esters 4, obtained from lactams, were condensed with indole-2-carbonyl chloride to afford the corresponding amides. Similarly, unusual conditions led to cyclisation at the 3-position of the indole moiety in the presence of pTSA and ethylene glycol to afford previously unknown pentacyclic derivatives 12 and 15.
