Nitroalkenes reacted with Meldrum acid in the presence of chiral amines to give the adducts in high yields and limited enantiomeric excesses. The highest enantioselectivity was reached at 20°C in the presence of cinchona alkaloids (ee= 20–25%). Unexpectedly, ee of the product was decreased by temperature lowering.
