The iron(II)-catalyzed domino isomerization of 3-alkyl/aryl-4-arylisoxazoles provides a selective access to a wide range of structurally diverse highly substituted indole-3-carboxylates. The operational simplicity, high atom efficiency, and the use of stable starting materials and an inexpensive and low-toxicity catalyst are some of the attractive features of this tandem double ring-opening-ring-closure strategy.

scheme or table, p. 1139 - 1142 (2010/05/02)
Chemical Equation Presented On the move: A palladium-catalyzed reaction of aryl iodides, diazo compounds or N-tosylhyd razones, and carbon monoxide affords β-oxo esters or ketones/ enones (see scheme; DCE = l,2-dichloroethane). The products are delivered with high efficiency through the title sequence.

On oxidation with thallium(III) nitrate in methanol, 1,3-diphenyl-1,3-propanediones 1 rearrange to give 3-oxo-2,3-diphenylpropanoic esters 2 and products derived therefrom.However, 1-(2-hydroxyphenyl)-3-phenyl-1,3-propanediones 1h-k undergo oxidative cyclization to 2-aroyl-3(2H)-benzofuranones 5.The alkali and acid catalysed cleavage of 5 is discussed.
