An efficient strategy for the mechanosynthesis of gamma-nitro dicarbonyl esters has been developed. A CaCl2-catalyzed Michael reaction, conducted at room temperature, afforded nitroalkenes from malonates in a short reaction time and in high yields. In most cases, polymerized side-reactions are eliminated or minimized. (C) 2013 Elsevier Ltd. All rights reserved.
