Coppola, Gary M.
, p. 1785 - 1787 (2007/10/02)
The reaction between N-substituted isatoic anhydrides and the carbanion generated from 3-methylthiooxindole 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.
