[reaction: see text] An unusualrearrangement of an O-aryl ether to an ortho-hydroxyaryl system was discovered during our studies on the synthesis of diazonamide A. We discuss the exploration of this rearrangement under mild thermal and both Bronsted and Lewis acid-catalyzed conditions.
An efficient synthesis of 3-hydroxy-3-(alkyl/aryl)indol-2-one derivatives has been described by the reactions of isatin with organoaluminum reagents. The reaction is very rapid and yields are high. The protocol is applicable for substituted isatins as well as a variety of organoaluminums. (C) 2013 Elsevier Ltd. All rights reserved.
