Abstract

Abstract The ease of lactonization of the γ-keto acids ArCOCH 2 CH 2 COOH is shown to depend on the nature of the aryl group: the presence of electron-releasing substituents on the aryl group results in a more rapid reaction as compared to the presence of electron- withdrawing substituents. The case of this cyclodehydration reaction is also shown to depend on the reagent used: acetic anhydride-sulfuric acid is a more drastic reagent than ...
