The reaction between N ‐substituted isatoic anhydrides and the carbanion generated from 3‐methylthio‐oxindole to produce the quinindoline ring skeleton is discussed. Analogous reactions of azaisatoic anhydride 6 and tricyclic anhydride 8 produces the 4‐aza analog 7 and pentacycle 9 . Some spectral data is also described.
