    • note
    • 6c saponification of 8 gave a mixture of structures, apparently including the phenol 7 and tautomeric unsaturated lactams expected from acetate cleavage, but with the methyl ester intact. Under more forcing conditions (15% NaOH, reflux 1 h), both the ester and the lactam were cleaved to give 2-(1H-pyrrol-2-ylmethylene)succinic acid, the diacid corresponding to the Stobbe condensation product 3.
