Mild, efficient, and solvent-free synthesis of 4-hydroxy-2-quinolinones

Malonic acid monoanilides were obtained in excellent yield from the reaction of anilines with Meldrum's acid under solvent-free conditions. The malonic acid monoanilide intermediates were then treated with methanesulfonic acid anhydride (MSAA) to produce 4-hydroxy-2-quinolinones in excellent yield. It should be noted that both reactions had to be run under mild conditions to avoid the decarboxylation of the malonic acid monoanilide intermediate.

Lithiation of N-(2-Alkylphenyl)alkanamides and Related Compounds. A Modified Madelung Indole Synthesis

A modified Madelung synthesis for the conversion of N-(alkylphenyl)alkanamides and related compounds to indoles, benzindoles, and azindoles has been developed.This procedure consists of treating the amide with 2 or 3 equiv of n-butyllithium or lithium diisopropylamide in tetrahydrofuran at temperatures from -20 to +25 deg C.Several examples where products other than indoles were formed from the starting amide are also reported.
