Synthesis of aryl α-keto-acids via the Cu-catalyzed conversion of aryl nitroaldol products
摘要:
Cu(II) salts efficiently catalyze the conversion of a variety of aryl nitroaldol products to afford the corresponding aryl alpha-keto-acids in high yields using 30% aq. AcOH:MeOH (1:1) as the solvent. (C) 2000 Elsevier Science Ltd. All rights reserved.

A palladium-catalyzed ortho-acylation reaction of azoxybenzenes with α-oxocarboxylic acids was developed in the presence of K2S2O8. The established methodology provides a direct approach to obtain acylated azoxybenzenes in good yields.
