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 p TSA and ethylene glycol to afford previously unknown pentacyclic derivatives 12 and 15 .
